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.

Great tee
Size: X-Large, Color: Medium Grey Heather
It’s a nice cotton material…not thin, just perfect. After washing, it also kept its shape.

Wonderful t-shirts
Size: X-Large, Color: Medium Grey Heather
These t-shirts are well made and have a nice thick feel to them. The sizing is spot on.
