Nice when sized correctly
Size: Large, Color: White
I used to be heavier when I started ordering from Amazon, so it’s suggested that I order size “Large”. The following two shirts that I ordered were a “Medium”.
I like the look, and comfortable fit.

Fit: Okay, Material: ...Sensory nightmare
Size: X-Large, Color: Black
I actually love how the shirt looks, the fit is long but I'm a pretty short girl.
One con that ruined the shirt entirely for me though is the material... It's grabby and not soft at all. I wanted a cute athletic turtleneck that would be breathable for a hot work environment. This is NOT it.. it immediately suffocates the skin. Sorry, I just didn't like it.
