DJs like Avicii tend to bring out the rave qualities in everyone, and we saw proof of that last night while capturing the outfits fans chose to deck themselves out in. Though there was snow falling (and sticking!) when the doors finally opened, you never would have known by the general lack of clothing. Many guests had some neon detail, but others just wore a simple white tee to be enhanced by the black lights in the concert. Sparkles, glitter, fur, feathers, body paint — really anything Ke$ha would rock was acceptable in the Bryce Jordan Center concourse.
