What should I wear to the game to impress him?

Tomorrow my school has the annual Student vs. Faculty Soccer Game and my crush is goalie for the student team. I'm going and I want to make a good impression and look cute. I'm also going to try to give him a hug after the game! What should I wear so I look cute but casual? It's going to be kind of chilly I think but it might warm up as the day goes on. Thanks in advance!!
