Purple was my first choice, but I looked weird in all the ones that I tried on. I settled on a mid-length white with a long sleeved shift to cover all the wide-ness of my ass.

Hm...well, it depends on if I'd have a Disney Princess wedding at Disney World or a wedding in a forest. If the first, then yellow because I'd be dressed as Belle and if the second, then forest green. :)
