What to wear to the concert?

Where clothes that you feel most comfortable in, theres no point dressing up. I went to a concert a couple weeks back and I just wore jeans and a hoody, I felt comfortable and I was jumping around dancing screaming singing although it did get kinda hot because of the amount of people that were there. I just took pictures and videos with my phone, but a cameras a better choice I guess. Take the one with the better quality. Have fun and make sure you know the words to the songs!!
