I was wondering if anyone who has made this costume could offer me some help. what sort of fabric did you use? I was going to go with lycra, but I've never sewn stretchy before and I would have to draft my own pattern and so far that's been a mess.
I think you could modify a unitard pattern, either for the top, or both the top and shorts. Then make your wrap with the same material. Kwik Sew has a women's active wear pattern that could be modified (3052 View A). Sorry I can't be of more help!
Update: I made some alterations to my drafted pattern and took the plunge and it actually turned out pretty good. I just need to do the leg-warmer things and I've pretty much got it in the bag. Thanks for your help!
