Is there a dress code am I allowed to water Bandanas on my head 8 years ago I had my hair up with it like a head band . Hair exsery . I don't wanna have to redo my hair at the door.

It largely depends on the show. Some shows have a no jersey policy. Ie no flying colors. If your bandana isnt solid colors you will be fine.

There were other attendees that had bandanas and baseball caps ,so I don't see why not 😊

I pretty sure you can, I've worn a bandana in somewhat recently and they didnt say anything.
