This is a set of Mochi-hada thermal underwear (L size) that I bought a while ago and barely wore. Mochi-hada is known for Washio, but this is Mochi-hada from Shirasagi Knit, which has a partnership with Washio. It's quite warm, so I only wore it when it was cold. Therefore, I didn't wear it very often, and it hasn't stretched out at all. It's highly elastic and looks small, but it fits perfectly when you put it on. There's no point in taking measurements, so please use my body type as a guide. When I wore it, my measurements were approximately 44cm for shoulder width and 95cm for chest circumference.
