For my Temari cosplay I took some fishnet stockings and cut them up to make the shorts. I put black elastic at the end. The leftover that I had from the leg I used to make the knee high one on her leg. I put elastic on top and bottom so that it wouldn't move so much. The fishnet is relatively easy to cut and doesn't fray you just have to be careful when sewing the elastic to the stockings. I suggest cutting it a bit longer than needed so that you can make sure that it stays put.

I lied. I used my imagination.
