I wear tops that are usually a medium, and I bought this one in a size M as well.It is very soft and comfortable to wear. The sleeves are just right for me and fit well. I'm 5'5\\\\\\\" and 146 lbs so I bought a size M according to their size chart because my main concern was the fit on my chest. The top is loose fitting, which is how I wanted it to look. It's great to wear at home and fits me every day.
