No brand. It's supposedly from some brand, but I bought it without a tag for about 5000 yen. I think the size is probably equivalent to a Large. The color in the third picture is the closest, a bluish-gray, denim-like color, and it's very beautiful. The fabric feels smooth and silky. The slit at the chest is deep, which makes your face look slimmer, and it's comfortable and very cute!
