Purchased at Futako Tamagawa Takashimaya S.C. for around 16,000 yen. Used twice. There's a snag on the back, but overall it's in good condition. It's a high-quality knit made of 70% cotton and 30% silk. Hand washable. It seems to be a free size, but it's small and fits snugly, so I've listed it as a size S. I think it's equivalent to a size 7 (Japanese size), suitable for someone with a slender build. It has 3/4 sleeves and doesn't get bulky, so it's also good as an inner layer for a jacket. It's a cute baby pink color. The second photo is the closest to the actual color.
