Cute wedding outfit for a young woman?

Hey, I'm 20 years old and really want to look cute for this wedding on Saturday... I live in a ghost town where the only stores to shop at are Wal-Mart, JC Penney, and Maurices... I have a white skirt that I want to wear since I have it already. Can you pick out a cute top for me? Then I'll go get it tomorrow! Thanks!
