Can my boyfriend go into the dressing room with me?

So my boyfriends going dress shopping for a party with me in a few days. So instead of him waiting in the outside the dressing room, can he just go in with me? No sexual activity will be involved, just wanting his opinon. He doesn't really like spending the whole day at the mall so I was thinking this would be faster!
