These pin up/1950's inspired high waisted booty shorts in monkey print were designed for my butt specifically. And I love them.
I took a long time to find that I didn't like the patterns online for shorts and I wasn't willing to give $80 plus postage for something I hadn't tried on.
The solution; design and make my own.
They're far from perfect even after doing several mock ups in scrap material and having my mother run her critical (annoying) eye over them.
What I've learned; make a smaller size when using a stretchy material; flare out the ends of the gusset (the connecting bit between the legs, also known as the crotch) to give better protection of my butt; try it on multiple times before sewing on the waistband.
So in a couple of months time, when I settle on a cosplay idea, I'll make the adjustments and (hopefully) make fewer mistakes.
1. Take measurements of waist, hip, lower hip, side (from waist to desired hem height), and around the thigh. And a measurement of the widest part of your butt from side seam to side seam only. Preferably have someone help out with this, my mother helped me.
2. Draw up the pattern of a front piece (cut 1), back (cut 2), waistband (cut 1), and gusset (cut 2). The back seam will be curved. If it's a straight line then it won't accommodate your butt, so divide the measurement of the widest part of your butt in half, that will be the apex of the curve as you draw the seam up to meet the waist. Also note, if you want to add a button on the hip, make the waistband longer than needed.
3. Sew back seam, overlock (a zig zag over the edges to stop fraying) and press (use iron to make it all flat).
4. Sew side seams, leave a gap for the zipper (the zipper should finish at the bottom of the waistband if you're putting on a button, or continue through to the top if no button), overlock and press.
5. Sew sides of the gusset (right sides together), overlock and press, then flip inside out.
6. Sew front of gusset to front piece, overlock and press. Sew back of gusset to back piece, overlock and press.
7. Try on, use safety pins to do up the zipper gap. If it's loose, sew in new seams on sides or the back seam.
8. Sew in zipper (or if there will be no button, do this after the waistband is in place).
9. Overlock leg holes and fold fabric over to create hem, sew (you're not going to hem the gusset, but marry the hem into it, because the fabric has been flipped inside out and the rough finish is hidden).
10. Iron on interfacing to waistband, sew to shorts (do right sides together first, fold it over, and then sew on through the back with a slip stich that won't be seen from the outside).
11. Sew on button (or zipper if you're skipping the button), make the hole in the waistband.
12. Dance monkey, dance! Or skate monkey, skate, because I made these to roll around in.
