GU This is a T-blouse with lace sleeves. The front is made of cut-and-sew material, and the back is made of blouse material (woven fabric). It has a moderate amount of room, and the sleeves also have just the right amount of space. It can be used both on and off duty. As shown in the third photo, it was slightly scratched by a ballpoint pen, about 5mm. It's barely noticeable.
