I bought this about three years ago, but it's never been used. I'm selling it because I have something similar. It's a finely ribbed knit with a high rib, made of rayon, nylon, and polyester, with excellent stretch. The neckline is sturdy and doesn't stretch easily, and the shoulders are knitted in a three-dimensional way for easy movement. Small slits at the sides and sleeve ends, along with a difference in length between the front and back, add a nice accent. It feels refreshing against the skin and is hand washable, so it can be worn alone or layered under a jacket in the winter. It has a lot of stretch, but it fits a bit snugly. It's a size S, but this brand tends to run a bit large. Length: Front 56cm, Back 59cm Chest: 82cm Shoulder width: 38cm Sleeve length: 60cm
