This is a set consisting of a light blue jacket and dress made of glossy fabric with a floral pattern. I purchased it about 20 years ago and wore it 4 or 5 times to weddings. It has been dry-cleaned to remove sweat and stored at home. The size is 40, which is a Japanese L, but I think it would also fit a Japanese M without being too large. Dress flat measurement: 94cm length Jacket shoulder width: 38.5cm There is a small stain on the right chest of the jacket, and some sweat stains under the arms of the dress, but I think they are hardly noticeable due to the pattern. The length would be around knee-length for someone who is about 165cm tall. Please understand that this is a used item. Two-piece set, suitable for invitations, parties, and weddings. It will be folded and shipped.
