Every obnoxious faux-raver chick wears this shit for their 'rave' (read: Avicii concert). Basically thrift a vintage t-shirt and make it slutty with scissors. I'd avoid wearing that unless you either live in a real backwater or don't mind crossing gender boundaries.
It's a cool idea in theory; unfortunately the sorority girls beat you to it.
Really? I imagine a scene/emo girl would be more likely to wear this to a post hardcore show than a "raver" girl wear this to EDC.
And it's supposed to be a ribcage but looking at it now it does resemble lungs.
