This is a back-open 2-way shirt from AEWENMATOPH. It's a T-shirt with a design that has a wide open back, and it looks very cute when worn with a delicate camisole underneath! Also, you can put your head through the open part and wear it as a different top. I'm selling it because I haven't had a chance to wear it. The color is black, close to sumi-kuro (charcoal black)!
