This is a long-sleeved white shirt dress from Natural Laundry. The size is 2, which I believe is equivalent to a size M. There is a string attached inside, slightly above the waist, allowing for adjustment by tightening. There are pockets on both sides, and the length is about ankle-length on a 162cm tall person. There are no noticeable stains. ★Regarding transparency: Patterns may be more visible through the fabric. Photo 14: The dress is placed tightly over a box of crayons with a pattern. Photo 15: The dress is placed loosely over a box of crayons. Photo 16: The dress is placed tightly over the entire box of crayons. The pattern is quite visible.
