Color: Black Shoulder width: 40cm Width: 44cm Sleeve length: 58cm Length: 63cm (All measurements are amateur, so there may be errors) Material: Polyester (synthetic fiber) Color/Neck: V-neck Transparency: Sheer Season: All season I haven't had a chance to wear it since I bought it, and it's been kept in the back of the closet, so it hasn't been washed. Nowadays, T-shirts and shirts are made in China, but this is made in Japan. I think you can wear it for a long time depending on the frequency. In winter, you can wear a bustier over it. Please consider purchasing only if you understand the storage period at home.
