What to wear at a rock concert?

I go to a lot of metal concerts such as Suicide Silence, White Chapel, Slayer, Korn, System of A Down etc... Personally don't wear anything you don't want to get ruined, don't take anything that can be easily stolen or ruined. I usually wear old cargo shorts an old short sleeve t-shirt and older shoes. It all depends on where you want to be too in contrast to the stage unless you are in seating, I am usually in the mosh pits. But if your in seating still follow my above advisory. There will be a lot of people there and it will be crammed full!!! It will also be loud and fun as hell!!! There is nothing wrong with what you want to wear though, just make sure it's not clothing you really like. Have a good time!
