@Prissi: Sorry I couldn't explain it better! Hope you work out a solution though! <3
For the wings, my local craft store sells large foam boards for like £5 each so I'm going to get two of them, cut into shape, cover in holographic fabric (found a perfect one!) at my closest Fabricland (they sell metre long feather boas too) and attach them!
I'm making my wings foldable and I hope my "method" works.... But I was thinking of attach snaps or velcro to the wings and leotard to hold the back in place, and using transparent thread and attach to wings discreetly so they wrap around your arms. I've done this with my Neo Queen Serenity bow/wings and did the job perfectly!
