What top to wear?!

I’m going to multiple Alabama football games with my boyfriend who is alumni of the school this fall. I bought these houndstooth flare pants from Walmart super cute and cheap! I was an Alabama fan before I met him but I don’t want to over do it since I’m not an alumni I love the pants on me but not sure what to wear for a shirt?! I have a lot of loose Alabama shirts that don’t really fit with the style of the pants but I also have one shirt that’s semi dressy but can also be dressed down. Just need some advice!
