I bought this in Taiwan, so the brand is unknown. It has slits on both sides, and the back is longer. The fabric is a bit thicker than a regular T-shirt. (It's about the thickness of a thin sweatshirt.) Length: 76cm Back is +9cm longer I've worn it several times, so there's some wear and pilling. Please refrain from purchasing if you are sensitive to these issues. Please understand that this is a used item before purchasing. Size: M
