My friend's daughter had this item dry cleaned for her daughter because it didn't fit, but her daughter doesn't want it, so I'm selling it. It's a size 9. There's no tag indicating a size other than 9, so I measured it. Shoulder width is about 36 cm, chest width (measured from armpit to armpit on the front) is about 46 cm, chest width (measured from armpit to armpit on the back) is about 45 cm, and the length is 96 cm.
