This is a winter innerwear item from Wacoal. It's very warm because it's a blend of acrylic. It stretches and fits well, and the neckline is open, so it's good for wearing under V-neck sweaters or sweaters with wide shoulders, as it won't be visible. The length is long, so it covers the lower back and buttocks, which tend to get cold. There are some areas where it appears to have stretched a bit, but for those who wanted to try it out, or for those who wanted a replacement, how about it at a low price?
