Unless they have actual women’s-cut shirts in plus sizes…I’m out. Sure, I can by a “unisex” cut that “fits”…but it’s like wearing a box.
However, I will say Teepublic does carry fat chick t-shirts - 4 styles, actually! - and I’ve been satisfying my inner nerd with many purchases. (Does that mean I’m turning my inner nerd into an outer nerd?)
