No, that's rude. Just wear a regular shirt. It's like going to a soccer match wearing a shirt who's from another teams playing. If you were in France they would tell you "Hey, You're not in the good concert", they would think you're there trying to be cool and not knowing anything about the band who sing or that you got lost and end up in the wrong concert. Lots of people would make fun of you.
