Avril lavigne concert help?

I am going to see Avril Lavigne in September (YES i knoww!!, Im just very very EXCITED!! as i love her) and i dont know what to wear?? I dont want to wear a jacket because its going to be roasting in there!! I was thinking maybe a Abbey Dawn WTH teeshirt with black skinny jeans and my black and white vans. Is this ok for a Avril concert do you think? any suggestions (sorry im just uber excited!! i love her this will be my second time :)!)
