Boxer Briefs

Not difficult

Great for men

Designed by Joost

Version 0.3 - YMMV

These boxer briefs combine style and comfort. I've worn no other boxers for years, and have about 40 pair of these.

Talking about pairs, these will give you all the support you find in briefs, without making you look like an 8 year-old boy.

Unless you are the type of person who likes to wear loose boxers (if you are, you're doing it wrong) your search for a boxer pattern ends here.

Not hard to make

If you have a serger, this pattern will be easy to make.

In the absence of a serger, you'll have a bit more work, but it will still be relatively straightforward.

Even if you have no sewing experience, help is available, so you'll be fine.

Designed for men

The dart in the front piece creates extra room at the crotch. Great for men, as they typically have extra bits there that need to be tucked away safely.

If you don't have anything to fill out that extra space, this pattern is not for you.

Design by Joost

This pattern is designed by me (joost) and based on my own experience of wearing boxers, and figuring out what works, and what doesn't.

Version 0.3 - Your milage may vary

This is version 0.3 of the pattern. It's been tested by myself only at this stage. That being said, I'm relatively confident you won't regret trying this.

This is great! Thanks so much! You've definitely put a lot of work into this project.

If I want to put a fly in the boxer briefs, do you think that will be difficult?


Submitted by joost on Wed, 11/26/2014 - 04:45

No, it would not be too difficult. You'd need to make some changed though. Possibly separate the front piece in two halves, to put in the fly.
I'll try to find some time to write up the changes you would need to make to the pattern to achieve this.

Awesome pattern. Surprisingly simple to put together even on a standard sewing machine. My question is I know your elastic is custom, but can you recommend any online sources for good waistband elastic? Finding the local options meager at best.

Thank you for the pattern and site. Looking forward to seeing what comes of it.


Submitted by joost on Mon, 01/05/2015 - 08:16

I'm afraid I don't have a real answer for that. The reason I had my custom elastic made in the first place was that I found it so hard to find good elastic to start with.
So apart from searching the internet myself, I have no real answer for you.

I'll ask around, and if I stumble on a good supplier, I'll include the info here.

Submitted by CharlieG77 on Fri, 01/09/2015 - 23:11

Thanks for the response. Who did you use for the custom elastic? Just curious.

Hi Charlie,
Here is the link to the info about the elastic on a (now defunct) old blog of mine:

Joost, Made the briefs and they sewed up real good. I adjusted the pattern by adding an inch to the top of the sides but that was all. Uset a Bernina serger and a Kenmore 158.19411 free arm for the hems. Stretch fabric. I may have pulled the waist elastic a little too much when serging, but the fit is good. Time was about 2 1/2 hours total including taping the pattern together including cut and sew time of about an hour for the first one. Instructions were clear and easy to follow. Pictures posted here:

Thanks Win, I'm happy to hear they came together nicely. They look great too!
Would it be ok if I include one of your pictures as a sample for other people to see?


Submitted by Win on Sat, 01/10/2015 - 16:22

Ok. I did not topstitch as I don't think that adds to the structure. Plan to make a few more. I have found sewing briefs patterned from store bought brands never turned out right. Your unusual pattern worked nicely and was easier to sew. I am going to add about 5cm to the top for personal comfort though I wonder if my saved measurements may require editing. I do not plan to make the tie as I never wear one.

Submitted by joost on Sat, 01/10/2015 - 16:26

The topstitching is purely a visual thing indeed. Glad to see it works for you, I'm really happy to hear they turned out good :)
As for adding to the height for personal comfort, I can relate to that. You can do so in the pattern options. Increasing the speedo rise will make them higher without changing anything else.
It's explained in the documentation here:

I found this Trailing through the internet, thought maybe it'd be helpful for every one If you scroll to the bottom you'll see boxer elastic. Not a bad price.

After a bit of a failure using fabric that wasn't stretchy enough, I have had great success on the second try with much better fabric. I used reclaimed elastic from some peter alexander briefs.

Submitted by bonj on Wed, 04/08/2015 - 11:12

I actually deviated from the instructions in one small area. In the double front piece, I sewed the darts on each piece individually and then placed them back to back with the serged/overlocked seams folded to either side. That way the seam is on the inside. Most commercial boxer briefs I own are made this way. I assume it is for comfort.

Submitted by joost on Wed, 04/08/2015 - 13:07

Thanks, that's a great tip. I've added your suggestion to the documentation:

Submitted by bonj on Thu, 04/09/2015 - 04:05

I just made another pair. This time, I rounded the top of the dart a little more and that removed the point I got on the top of the dart in the previous pair. I have been using cotton lycra and it is very similar to the fabric on the no longer serviceable commercial pyjama briefs I reclaimed the top elastic from.

You should post pictures :)

Don't mind the cat hairs and the dodgy zigzags on the yellow elastic... The black elastic is just as bad, but it's hidden. I didn't have yellow thread.

Black waistband is 1st pair. Yellow waistband is 2nd pair.

Great, thanks so much! I'm going to add these to the examples page for this pattern that I should finally set up.

Submitted by fkv on Mon, 04/27/2015 - 18:55

Hi Joost,
the side seams between back (1) and the side panels (3) does not seem to be same length, see pattern 4a1f672029bffbae1325c52667e65b9eb9079e96
I would assume they should match. Am I missing something or is this a glitch in the pattern maker.
Besides that, just to let you know that your videos inspired my to try more challenging stuff than just taking in store bought trousers.

Submitted by joost on Tue, 05/05/2015 - 14:15

Hi Filip,
I am not actively checking the side seam length. Its length is the result of a bunch of other calculations.
While I could check it, that raises the question "what do I change to fix it" and that is harder than it seams.
Maybe it's just my lack of experience as a pattern designer showing, but I have made a pattern for my own boxers with a lot of trial and error.
This pattern is my attempt to make that 'work' for everybody, but it's by no means perfect.

Until I can find a better way, I would suggest you stretch the side seams to make them the same length ;)

Submitted by jk6026 on Mon, 05/11/2015 - 03:54

Joost, I ran across your site the other day as I was searching for men's boxers patterns. I am new to sewing and recently got an over lock machine, now I have been able to put it to good use! Thanks for the inspiration. I made three pair over the weekend and while they are by no means perfect, they fit me perfectly thanks to your pattern maker. I had no problems with the back or side panels not meeting up. I am going to have to google how to do the top stiching as I do like the look it gives and I went with your suggestion of the rayon...worked great! Don't think I am ready to tackle the pants just yet..hahaha

Check your Paypal, sent you a donation for my thanks,

Thanks again for the inspiration,

IT would be good if we can get pattern for ladies shorts.


Submitted by joost on Fri, 07/03/2015 - 15:43

I'm not sure what exactly you mean by shorts. Underwear shorts?
If so, I have considered it, as I think it would not be too difficult. But to be completely honest with you, I'm a little overwhelmed by work at the moment, so while it's on my mind, it's not exactly on the horizon.

Awesome patterns! I am a novice and have had no problems at all with the pattern, or following your directions. About the boxer briefs, I do have one question, how would I go about making the pouch larger so as to give my man bits more room?

Submitted by joost on Mon, 11/23/2015 - 11:48

Hi there, nice to hear it worked out for you :)

To add room in the puch, you can reduce the dart the runs of the center front piece. You could also add a bit to the (curved) side seams of that piece.
Both alterations will result in more fabric available in the man bits area.

Please let me know if this is too abstract, and I will see if I can make some sort of quick sketch to clarify this further.


Submitted by SimpleSew on Mon, 11/23/2015 - 22:10

That's exactly what I did. Guess I remembered a little from Home-Ec after all.. After I submitted that question, I looked at the pattern and thought that adding more to the inner curves would do the trick. I would send a pic, but I used old t shirts to practice with, so they're not so pretty...

Thanks again!!!!

Thank you so much for making this available! My partner is very tall and thin and it has always been tricky finding things that fit him right. I just made these and they are near perfect! Next pair I might try making the front pouch a little bigger, but all-in-all, a success! I'm looking forward to trying out some of your other patterns.

I partially finished my first pair because it became apparent, after trying on, what some of the measurements really meant on my body - like speedo rise and negative ease. So I generated a second pattern with revised fit measurements, made the briefs, and love them. Delightful! Here's a few notes to help others that may attempt this pattern:
-- I wear mine as loungewear/sleep shorts and prefer them loose instead of tight to my skin. I set both negative ease numbers to zero. Worked perfect to give me the slight loose fit I like.
-- I don't have a serger (yet) so I did this with my regular machine. Jersey knit needle and a good stretch stitch worked well. I also topped stitched to hold all seam allowances down.. Top stitch in contrast color gives nice effect.
-- I used the "bonj" alternative for closing the front darts... Nice clean look.
-- Suggest matching the paper pattern side seams to ensure all hemlines and waistband lines align.. I found a bit of misalignment in my pattern's hemline, but used a bit of extra paper, tape and ruler to make everything line up. Worked like a charm.

I've posted some pics on you Flickr site. (Black with blue band)

Thank you Joost for creating this. I'm definitely gonna make more. And now that I understand how it fits me, I can tweak to make other variations.

all your hard work to create patterns and a system to deliver them that, as far as I know, is unique on the net.
I'm a complete novice at sewing (but learning quickly). Your Boxer Briefs pattern enabled me, with my limited skills, to cobble together a wearable pair of briefs. The only material I had available came from two paint spattered, jersey knit T-shirts that had already seen a decade of hard use.
I plan to buy some better material, play with the measurements and make some more in the near future. I don't have a serger but this pattern offers me an affordable and fun way to wrestle stretchy fabric into submission while learning new seaming methods on my entry level sewing machine.
Thank you again.
PS - I'm a retired guy, living in rural Canada, and haven't had a need to wear a shirt, tie, suit, jacket or real slacks in 15 years (don't own any one of them anymore). My high style is baggy jeans with knit shirts and fleece pullovers. I found sites with dozens of interesting designs for SHACKETS on the net (just Google the word "Shacket.") When I gain more skills I just might try your Singular Shirt pattern as a base for my own Shacket or maybe, by that time, you'll already have a pattern for that. All the best for the future.

Thank you Richard for your kind words. It's a heart-warming read.

I hadn't heard of a shacket before. Might be a good step between my shirt pattern and a jacket pattern that I eventually hope to do :)

Do you have any tips on how to make these into long underwear pants? Would it be possible to get a pattern for that?
These work great as boxer briefs, but here in the cold long underwear pants are really needed, and I can't find a pattern anywhere. I get confused how to add lenght to the legs, because boxers are made of so many pieces..
Otherwise this pattern works well, if the measurments are taken correctly. Thanks!

Submitted by joost on Sat, 05/21/2016 - 19:59

I think your best approach would be to extend these by sewing on a separate leg piece where they are hemmed.
That should be rather trivial, and certainly easier than extending the individual pieces to extend down your legs.
Do you think you'd be able to figure that out, or do you need some pointers?


Submitted by Stachelhaut on Thu, 06/02/2016 - 19:23

Hello Joost,

I just finished my first boxer briefs. Great fit, very comfortable. Thanks a lot.

Same thing here: "the side seams between back (1) and the side panels (3) does not seem to be same length, "

Your solution worked, no problem at all: "Until I can find a better way, I would suggest you stretch the side seams to make them the same length ;)"

The next briefs I make will have a seam on the upper end, and a (narrower) elastic inside the seam. Cheaper, easyer to make and repair - friendly, as the elastic is not sewed but just pulled in.


Ps: I used a thin single jersey, 95% viscose, 5% spandex.

Submitted by joost on Fri, 06/03/2016 - 10:46

Glad to hear you like them. I like the exposed elastic because it adds a bit of a masculine touch and... well I have pretty kickin' elastic :)

Hi Joost!

I found your site via a facebookpage (naaien voor vriendinnen) where the ladies were complaining about the lack of proper patterns for boxers for their partners, until one internetsavvy woman found your site (so expect a bit of traffic the coming days, these ladies mean business!).
I've been using an old pair of boxershorts as a pattern, which I ripped apart, but it was never quite right (probably because it was a very old pair, and my boyfriends body had changed a bit since purchasing said pair, judging by the discoloring of the fabric).
I'll add/send a picture of the pair I made, because your examples page is lacking a decent pirate print xD

One thing I changed about the way I put them together is the double fronts. I folded both fronts seperately down the middle, with the print on the inside. Then I put one on top of the other (so you have two folds on top of each other) and then I serged the dart. When folded open, your seam is not only wedged between the two fabrics, but since they are sewn together, you don't get shifts if you decide not to topstitch the center front. Also, this way you have the print on the inside too (which doesn't actually add anything to the pattern, but is just a quirk of mine).

Thanks for this awesome pattern, I will definitely be using it a lot!


Submitted by joost on Fri, 08/19/2016 - 17:34

Hi Irene,

Thanks for the warning. It's always good to know when you are about to be swamped by ladies who mean business :)

Glad to hear you like that pattern. Also, clever hack at the front, although I personally prefer to not have the print on the inside because it always feels less soft.
Good to know that you will be responsible for assuring a minimum amount of pirate print. That was arguably sorely lacking!

Why do you ask for the trouser waist size instead of your measured waist for boxer shorts? I just made a pair for my husband based on his pant size (32 inch). They were too small. when I measured, he is 36 inches. I made a 34 inch pattern and they fit much better but look like the seams are stressed a bit much. I am now making another pair that is a 36. Also, I had to add 2 inches to the waist to waist measurement to make shorts fit how he wanted them. I left the speedo rise at the 3 cm default. Should I have increased/decreased that instead of increasing the waist to waist measurement? Once we get the fit correct, I'm sure these will become his favorite. I make my own and use a roll technique so no seams are next to your skin. . I'm trying to do that with this boxer pattern. A bit more difficult with the curved seam. Also - regarding elastic...I am using a 1-1/4" plush elastic for the waistband. Works great! I'm able to get it in multiple colors.


Submitted by joost on Tue, 01/03/2017 - 06:47

Dear Mary,

I am sorry about the confusion, the trouser waist measurement is the circumference of your waist at the height you wear your trousers (or in this case your boxers). The documentation for this measurement illustrates that.

I must admit I never considered that one would confuse a measurement with a garment size, but I can see how you find the name misleading. I will address that in the future.

Meanwhile, 36" is definitely the measurement you should use. And if your husband wants the boxers to sit a bit higher, you should increase the rise. If he felt they were cutting into his bum, increase the cross seam.

The relevant documentation is here:


I hope this will be helpful. Thanks for your feedback and good luck

Thank you so much for this amazing pattern. My husband was just complaining about his current boxers and about the last pattern I had tried. Not enough 'lift and separation'. These give him the exact fit he was looking for. My pattern was a bit off - the inside straight edge of the inset piece was about 2 inches longer than the Front piece when they were sewn together, but it was easy to trim off. These are made from a cotton lycra. I'm looking forward to playing around with some of the rise and ease options. I see many more in his future!

I made my husband some boxers out of old and unworn t-shirts, using the logo and pictures on the front for the big piece at the back. He is very proud of his logo'd pants! He says they are the most comfortable boxers he has ever worn. He is now after a homeboy hoodie. That you Joost for your expertise and generosity, your instruction are fab too.

But I found a way to adapt this pattern to my own body. One thing I stumbled across though is that the printing-size-check-box ("The (white) inside of this box should measure 10 by 5 cm") only measures 9.4 by 4.7 cm - even in the original (non-adapted, non-converted, non-printed) svg-file. I made it work by scaling the back piece up a bit (I had already cut the rest at this point) and trying to use very small seam allowances. Here's the result:
