chick halloween costume?

At my high school, they let everyone dress up for Halloween. This year, some of my friends and I (one boy and six or seven girls) are going to be Colonel Sanders and his "chicks" (play on chicken/hot chicks). We already have his costume picked out (yes, he's a little fashion challenged), but we're not quite sure how to make our costumes. We were thinking of doing some sort of long-sleeved white leotards with yellow tights, but obviously we need to use feathers too. (We also need to cover our chests if you get me. White leotards. Yeah.) We would also like to do some kind of cute skirt.

Please keep in mind that we go to a Catholic school, so our costumes need to be pretty modest. We want to look cute, but not skanky.

Any suggestions would be helpful. Pictures, links, costume patterns, ideas, etc. Thanks so much!
