This is a proper dress. I bought it 8 years ago and wore it about 7 or 8 times, but I'm selling it because the size no longer fits. It says size 3, but I think it's a size 11 (Japanese size). The lining is pink, so it showed through the fabric and was cute. Shoulder width: 36 cm Width: 45 cm Length: 94 cm It has a side zipper. I had it dry cleaned, but it has been stored at home for a long time since then, so please understand. I will compress it and pack it small for shipping.
