Purchased in Italy and worn a few times, then hand-washed. The back has elastic and adjustable shoulder straps, so I've listed it as free size. The tag says XS, but it's a bit different from Japanese sizing. ↓ For reference... It should fit someone around 150-160cm tall. For someone 155cm tall, it will reach around the ankles.
