Team spirit award help!

We're having a competition at my gym, we're all CrossFitters and we're in teams, my teams team name is Swolemates. Every Friday night we do the CrossFit open work outs, we get points for placements in top three but we also get points for team spirit, this last Friday's team spirit winners had beauty and the beast theme and the girls got red bows and yellow tutus and cute shirts that said train like a beast to look like a beauty or something like that and the guys had shirts that said beast. Anyways, I need something cute that won't cost a bunch of money and not be an insane amount of effort as I'll most likely be the one doing the work. There's only two ladies (including myself) in our team and the rest of them are men, if that matters.
