What should guys and girls wear here?

Birthday suits

I wear everything from sweatpants to jeans and a t-shirt/jacket to no shirt at all. It really depends on the show and the genre of the set that night. Casual clothing you'd wear out to a bar would suffice here.

There is no dress code. If you're going for an EDM concert, you're going to see a lot of rave outfits.

Yeah, I basically just wore shorts and the shirt didn't matter because it came off 😄

If the show is gonna be packed, wear something that you can stay cool in, because it gets unbelievably hot.

Honestly for me that depends on what type of concert you are going there for. I went to a rave there last time so I wore a rave outfit. They don't have a strict dress code there at all.
