Welcome to sewing for boys month on the blog! It’s been a while since I’ve showcased stuff I’ve made for my guys here, so all month long we’re going to be focusing on them. And can I say, y’all, that I love the current fashion sweatpants trend? It’s the perfect warm and comfy look and I will be sad one day when it is declared out of style. My boys wanted in on the trend too (they look at my boys fashion Pinterest board with me sometimes to give me ideas) and so today I’m sharing the Slim Sweats pattern – a pair of boys sweatpants that’s super easy to sew with just enough detailing to be right on trend.
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, see below

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.
