Retail price approximately 4000 yen. The size is free, but it's large enough for someone who usually wears a size L. The length is such that when worn by someone 153cm tall, the hem touches the top of the foot, and with shoes on, it's about the length for a no-cushion fit. I bought it while out, so I don't know the name of the store. I've worn it about 1 or 2 times. The size is free size, but it's easily equivalent to a size L.
