Will be a favorite go to if…
Color: White, Size: X-Large
Great soft easy wear shirt. Through no fault of its own, if you have a big belly you might want to size up. I’m not going to punish the shirt with a star deduction for that. A slight belly will happily put you in your regular size category. Other than that, this will probably be one of your reach for fav’s.

Awkward fit
Color: Light Khaki, Size: Medium
A bit of an awkward fit in terms of size of arms, chest, and stomach. If between sizes I would probably recommend sizing down.

Great for women and men. Crotch isn’t too low and not too baggy for women.
