Size: M Shoulder width: 36cm, Body width: 47cm, Length: 58cm Material: Polyester (synthetic fiber) This is a geometric patterned cut-and-sew top from ESPRIMUR, designed for adults. It's incredibly lightweight and smooth. For those who often raise their arms, such as when holding onto straps on trains, the armpits are quite visible. If you're concerned, it's recommended to pair it with a French sleeve bra top that can also absorb sweat. Instant purchase is OK! (^_^)/~~
