A T-shirt paired with jeans is an acceptable outfit for a rock concert. Wear comfortable shoes that allow for jumping and dancing.
Jeans and a T-shirt are a great start for a rock concert outfit, but the accessories are what really pulls the ensemble together. Guys can wear a baggy shirt featuring their favorite band's logo. For the ladies, a black tank top or basic shirt paired with bold accent pieces, such as chunky jewelry with skulls or studs, works great. Both sexes can top the outfit off with a classic leather jacket if the temperature will be cool.
