Also, they’re perfect for a game of basketball with your brother. So perfect that if your older brother is skinny he might steal a pair of yours.
To make the Slim Sweats you’ll need:
- 2/3 yd of sweatshirt fleece or other knit fabric (at least 10% stretch).
- 2/3 yd of rib knit fabric
- 22 inches of 1 inch wide elastic.
- The pattern…
The pattern is in a kids size 5. If you need to make the pattern bigger or smaller, check out this post. To get it, click your preferred option below to get the free pattern only as a newsletter subscriber, or to buy the digital pattern + printable instructions for $2.

Place the cargo flap pieces right sides together with the lining (I used some thinner scrap knit i had for lining; you could even use woven fabric here). Sew around the edges of the flap, leaving an opening in the top straight seam. Clip the corners. Turn the flap right side out and press. Topstitch if desired. Repeat with other flap. (Note: pockets do not have to be sewn with a stretch stitch)
Fold the cargo pockets right sides together and stitch the pleat for about 1/2 inch. Open, press pleat flat, then pin the pocket to the lining. Stitch around, leaving an opening on one side to turn the pocket. Clip corners, turn pocket and press. Repeat with other pocket.
Stitch pockets in place, making sure to backstitch at beginning and end.
Stitch flaps on top of pockets.
Sew along the seam marking for the mock fly. Use a basting stitch from the top to the red box in the image below, then backstitch, then switch to a zig-zag or other stretch stitch length for the remaining seam.

Open the pants with the wrong side up. Fold the flap over to the left and stitch along the fly curve. Make sure your bobbin thread is the color you want, as this stitching will show on the front side.
Use a seam ripper to remove the basting stitches and complete the mock fly.
Sew the back rise using a stretch stitch.
Fold the pants right sides together so that you can match the crotch seams. Pin them and the inseams as well, then sew both inseams in one long seam, using a stretch stitch. Turn the pants right side out.
Fold the waistband in half, matching the short edges. Stitch, using a stretch stitch.
Fold the cuffs in half, right sides together, PERPENDICULAR to the fold line and match the raw edges. Sew the side seam. Fold on the fold line and match the raw edges, creating a tube. Place this tube around the leg of the pants, matching the seams. Sew with a stretch stitch through all 3 layers (2 cuff layers and 1 pant layer). You will need to stretch the cuff slightly to fit.
Apply the waistband in the same manner as the cuffs, EXCEPT leave an opening to insert elastic.
Using a safety pin through the end of the elastic, insert it in the waistband, being careful not to twist. Sew the elastic ends together, overlapping 1 inch. (Note – you may want to check the elastic length on your own child. For Bean I had to shorten my elastic to 20 inches before sewing). Sew the opening of the waistband closed and you’re done!
Now throw on those sweats and find a pickup game. Preferably in the mud.

These are absolutely the cutest. Thank you so much for sharing with us!
these are so great! I love when you showcase your boy sewing. There is so much girl sewing, but never enough boy sewing! Thanks for the pattern!
Love when your feature sewing for boys! Love the style with the fly front and cargo pockets. Thank you so much for the free pattern.
Loving these! My grandson is too little right know but I know how fast time passes! I need to make a few different sizes for the grandma box. 🙂
Thanks for shareing these with us!
I totally agree with Kristie. Thanks for this pattern!!!
Those are really great! I think with just a little work, they’ll fit my 3 year old son. I’m so excited for your sewing for boys month!
Wonderful! This is perfect for my boys–just the kind of thing they love to wear.
Thank you for the PDF pattern, for the Slim Sweats. I look forward to making them for my grandson.
Aw Melly these are so great!
Thank you so much! I sewed them up yesterday for my guy (he is a very slim size 5/6 so it was perfect) and I can’t wait to get them on him this morning. I left off the faux crotch and pockets, but they still look great!
Just curious where you got your sweatshirt fabric from? I don’t know why I’m having so much trouble finding any!
The light gray is from an old pair of my sweatpants, I cut around the stains 🙂 The darker grey is sweatshirt fleece from Girl Charlee I believe.
Thanks! My son will love these!
Awesome! I have two skinny grandsons lol. One will take the pattern as is for sure. The older one will just need it lengthened. And maybe a little bigger. He is a skinny 8 yr old lol.
Thanks so much for these! These are so good – I made them for my 4 year old and they’re a great fit with room to grow. And I found the instructions so easy to follow. I’ll be making several more of these as he does a lot of sports and I prefer him in sweatpants rather than more restrictive trousers such as jeans. Thanks again!
Thanks a lot for thuis tutorial! I already made 2 pairs for my 5 year old boy. I added a little lenght. And they turned out perfect. He is so proud. I usually sew lots of things for his little sister. It is so hard to find Nice boys patterns.
Kind regards from the Netherlands

Thank you (again) for the great patterns and the eye-opener to use old sweatpants!
Thank you, Melissa. For your talents and knowledge to share with us, the sewing public!!!
