Q&A for How to Make Shorts

You'll need a measuring tape. Then you'll need to measure around your waist or hips (where the shorts will sit), the length (from the top to the bottom of the shorts) and your inseam (crotch to bottom).

You're going to need to increase the width of the leg and then either gather the leg openings or run elastic through them.

You can with an elasticated fabric. Take your measurements as usual, and make sure that you do not make the leg cut so high that they seem like briefs/knickers. Use a zig-zag backstitch to allow more stretching when it comes you your gymnastic movements. Applying talcum powder before putting them on will stop sweat from tightening the fabric.

Make them more high-waisted, and with a shorter leg seam, similar to booty shorts. I am a trans girl myself, and this helped me with passing.
