Julia: Well, have you heard of the song "Gee"? ;D
Alyssa: Ah, I think the gang outfit might be better than the school one if you're in a rush. It just looks like a plain black hoodie and a white t shirt, and then buying fabric at Joann's for the scarf is fairly easy, and then a pair of nice jeans. Maybe check Target? I know they sell packs of those men's undershirts in white, and I think one of those would work. And those shoes look like they'll definitely work, his shoes aren't particularly important.
