this is such a beautiful and simple lace cami by the japanese brand, “castanets club” made in the early 2000’s / y2k era. there are iridescent buttons that are fully functional, and there’s an extra on the size tag as seen in photo 4. the color is also most accurate to the. 3rd & 4th photo. the ribbon tie is functional and flatters the bust really well. no known flaws, and in perfect vintage conditions. marked a jap m, best fits a small with stretch.
