Help me with our pref!

Okay, here's the deal.

My chapter has been doing pref round the same way for a long time: the entire room draped in black with white Christmas lights, and all the girls in black cocktail dresses. We love our pref ceremony and don't want to change anything about the ceremony itself, but on this year's recruitment evaluations, a lot of the new members said they didn't like how dark it was in the suite.

So in short, we want to change the wall drapings to white with blue accents. The problem is, what the heck do we wear? White dresses are a no-go, because several sororities on my campus do that and it always looks terrible. Black dresses look better on people and it's not as hard to match.

Any ideas of what to wear that would match blue and white walls?
