Runs small
Size: XX-Large, Color: Navy
Definitely go a size up. These run a whole size smaller than designated. Material is also heavier than a regular t-shirt. Quality seems okay

Fits well and comfortable!
Size: Large, Color: Eggshell White Black Mariner Stripe, Size: Large, Color: Eggshell White Black Mariner Stripe
This shirt fits my husband very well, it is true to size. It is soft and stretchy enough to be comfortable. I bought this as part of a costume but my husband wears it around the house now because it's so comfy.

You get what you pay for
Size: XX-Large, Color: Eggshell White Black Mariner Stripe
Like most of the other reviews here, the shirt runs too small and too short. Material was also incredibly uncomfortable. It also wasn't the color I was hoping it would be, but that's on me for not reading the fine print (eggshell white was very much not white)
If you're looking at this for a certain costume/cosplay idea, it's probably not what you're looking for.
