Is it ok to wear opposing team's colors on campus?

So I've been a fan of Team A for all my life and like their athletics much better than Team B. But unfortunately I'm going to Team B's school because they have better academics. So I have a TON of clothing from Team A and I don't want to give it all up when I'm going to school at Team B. Is it ok to wear Team A's clothing there? I know some people might get all up in my face about it but I'll be supporting Team B's school but that doesn't mean I still won't support my old team.
