It has a tight fit, which is positive because the thermal wants to "stick" to the body, but for me the sleeves were short. It has relatively thick fabric, so it is good to wear something looser on top so it doesn't show lines. It definitely keeps you warm, so it's value for money!

The only complaint I have is that I wore it all winter and due to constant use, the material started to fray and white patches appeared on the inside. However, because I wear it under other clothes, this didn't bother me. Overall, it is very comfortable and provides some warmth. The big plus for me is that the fabric allows the skin to breathe and I don't feel like I smell bad even after wearing it for many hours. It is definitely worth the money

For the job I need it, it is perfect. It keeps me warm, I don't sweat, simply very good. It was worth getting it.

Very soft, warm, and comfortable blouse. I wear it underneath the sweater and it keeps the body temperature well. Good quality and price ratio.
Edit: After a few washes, the sleeves shrank a lot until they reached 3/4 length.
