This is a summer shirt from Natural Laundry. The sleeves are 3/4 to 7/8 length. [Color] The main body is a thin blue and white stripe, with solid color piping (about 1cm wide) on the sleeves and hem. [Size] Labeled as "2", so I've classified it as a size M. Width: Approximately 46cm Length: Approximately 62cm Sleeve Length: Approximately 42cm [Material] 100% Cotton I purchased this at a store quite a while ago. The material is like gauze, very soft and comfortable against the skin. It's lightweight, and I loved the color and design, so I wore it often. It might look like it's missing a button, but that's the design (see photo 6). It may be considered vintage, but there are no noticeable stains. Thank you for your understanding. Please consider purchasing.
