This is the JILL STUART Ally Shirt Blouse. Size: S. Retail price: 20,900 yen. I fell in love with this simple and very cute blouse and bought it, but it didn't fit after wearing it once. Since I don't think I'll wear it again, I'd be happy to pass it on to someone who will wear it while it's still in good condition. The black ribbon, which is the detachable collar, and the sailor part can be removed with buttons, so I think it can also be used as a regular white blouse for formal occasions. Immediate purchase is welcome, and I will try to ship it the same day! Here is the product description from the HP: Shirt blouse with a detachable big collar. It is made with a double collar, and the lower collar part can be removed depending on the style. The cuffs and hem have a round curve slit, giving it a relaxed design. With a sharp collar as a key point, it can be matched with skirts and pants.
