Used once for a short period. This is a check shirt from LEINWANDE, released in the fall of 2023. It is indicated as 100% cotton. The edges of the ruffles are raw. It's difficult to see in the images, but there's a matching fabric string running from the collar to the body. This string comes out from the hem of the front and can be pulled to gather the fabric and shorten the length. Here's the product description from the store: ▶︎Multiway Style: Uses a casual flannel check fabric made with thick, pre-dyed yarn. The generous gathering on the collar is impressive against the masculine appearance. You can tie the ribbon or wear it casually as a collarless jacket. The cocoon shape on the back is also a key feature. This is a piece that expresses the season's theme. ▶︎Shipping: Will be shipped as compactly as possible. Transparency: None Season: Autumn/Winter
