I don't know why you are asking for recommendations of stores. Check your campus or ask your Rho Gamma how dressy each event is, and wear something to that effect that is your style. If a chapter only likes you because you have a Lilly dress, is that chapter actually a good fit for you? Not to pick on Lilly, because if that is your style, then you should wear it. Do you want to feel like you have to constantly keep up with certain labels and stores in order to fit in with a group of women who will be your sisters?

I will agree with previous posters that your outfits should be tasteful and flattering, but I don't think you should buy clothes from a store that you normally wouldn't for a similarly dressy event.
