This is an all-in-one from CHILD WOMAN. I bought it a few years ago and loved it, but I haven't had a chance to wear it, so I'm selling it because it's a waste. I only tried it on at home. The back of the waist has elastic, and the collar is an open collar type that makes it easy to look neat, so you can wear it in a mature style. Made of linen, it's perfect for the upcoming summer season. With pockets. The size is listed as free, but the waist is quite fitted, so I think it's safer to consider it a size S-M. The seller, who usually wears S-M size clothing and is 161cm tall, found it to be a perfect fit. Disadvantage: The front is buttoned, so you have to open all the buttons and the zipper at the crotch when taking it off, which is a drawback. Going to the restroom when you're out and about might be quite difficult. If you don't mind, please consider it. Material: 100% linen Size: Length: 139cm Length from waist down: 91cm Waist: 39cm Inseam: 54cm
