This is a short-sleeved blouse from GU. I've worn it twice and hand-washed it. It's a beautiful item with almost no signs of wear. It's a size S, but it has a generous width, and the shoulders are dropped, so I think it would be fine for someone who wears a size M. There's no zipper, and you put it on over your head, but it's not difficult to wear. It's a calm pink color, not flashy. There is no lining, but the material is not see-through. Size S Width 48cm Length 56cm 100% Polyester Color: Pink系 (Pink-based)
