Okay full disclosure here, I got this for a cosplay and don't work in a lab environment where I'd need this for my job. That being said I really liked this labcoat! I wanted something that would be long enough to reach near my knees but I also wanted it to be more flattering than standard boxy unisex styles. This was exactly what I was looking for. I'm 5'9" 170lb and ordered a small. Definitely recommend if you need a labcoat for any reason :)
