Thank you for viewing. ・This is a simple black tank top with a balloon-like silhouette. ■PLST Polyester Stretch Back Chiffon Cut-and-Sewn ■Size M ■Main fabric: 96% Polyester 4% Polyurethane Separate fabric: 100% Polyester ・The inside is shaped like a tank top, and the material from the shoulders to the back is slightly sheer. The back is not see-through. It's like wearing a see-through material on the shoulders (I apologize for not being able to express it well). It feels good against the skin. Also, I think it looks slimming and stylish. I wanted to wear it, but the size doesn't fit, so I'm selling it. ・I only tried it on and have stored it at home. Thank you for your understanding. Basically, shipping is closed on weekends and holidays. Regarding the number of days for shipping, I have allowed extra time, but I try to ship as soon as possible. Thank you.
