On Wednesday, I'm having lunch with a friend of my stepdaughter. She's a nice young woman, mid-20s, who has been asked to dance at a friend's wedding. She has been told that she needs a costume that incorportes VERY SPECIFIC colors, to go with the bridal party. IMHO, it's a kind of weird color combination -- grass green, light brown, goldenrod yellow, and silver-gray.

Any recommendations for places to get costume pieces / fabrics / whatever that aren't too pricey, lots of available colors, that won't take too long to get / make?

Thanks for the help, guys!
