Thank you for viewing. I purchased this at a store in Ginza for about 30,000 yen. The size is listed as 4. I've only tried it on, never worn it. I believe the size is M. The neckline is open, so it will make you look very glamorous. It's also great for clubs and other events. Please refrain from purchasing if you are sensitive to items stored by a non-professional. I am open to price negotiations, so please consider.
