Reply to What to wear at concerts?

So I'm going to my first concert ever tomorrow evening , rusko. I somewhat dislike dubstep nowdays but it's with a friend I havn't seen lately so I wanna go more to just do something with him.

Anyway, what I've read it's like all white is usually the go to color but other opinions would be awesome. I have white jeans and a white shirt I can wear but
should I wear something nicer for the ladies, or does it really not matter? Not sure if a button down shirt that I roll up the sleeves in is too formal for the dubstep scene. I don't believe it's a big show, as tickets are only $20.

Any help would be awesome, sorry to believe this through so much.
