1. Clothes: Jean shorts, a t-shirt, tank top or anything you find comfortable in hot places( all the people around you will cause body heat and you will get very hot ).
2. Shoes: wear high top converses or any sneakers you have. But make sure the shoe laces are short so people wouldn't step on it during the concert ( you might fall if someone did ) . DO NOT wear flip flops because people will keep stepping on your toes and you will be in pain during the whole concert.
3. Hair: Wear your hair up like in a high ponytail or a cute French bun.
4. Make up: If you wear make up, wear liquid proof eyeliner because if you sweat you don't want it to get messed up and also wear some lip gloss. You can wear a sexy smokey eye if you want.
