Wear what you like & feel comfortable in. I like to wear music artist tees

A simple chic outfit with a statement accessory/jewelry and a comfortable hairstyle, preferably an updo. Light makeup with a bold lip or cat eye.
This is just my own idea. I just like dressing this way when going out with friends and although I've never been to a concert I feel like it's fairly good for concerts too.
