Looks like the top of a diving suit. post #692447

Nice lens flare, needs more dubstep though.

I've seen this kind of shirt in several pictures, so I looked it up. It's a swim shirt, or a rashguard (and tagged as such on Pixiv: ラッシュガード). I'm tagging them as swim_shirt for now, since I'm not quite sure if rashguard is a brand name or just the clothing type.
