This is a roughly knitted cotton knit. It's a compact fit, and I'm 170cm tall with an average build, and the sleeves come to about my wrists. The knit has a loose weave and is stretchy. In winter, you can wear it with a turtleneck or other inner layer, and when it gets warmer, you can wear it over a tank top. I've only worn it a few times, so I think it's in good condition, but it has been handled by someone else and inspected by an amateur, so please understand this before purchasing. ☺︎
