As a tall guy I have bought from them before. Their in house "King Size" brand is pure crap. I bought three of their polo shirts and was very disappointed. The fabric is cheap to the point where after a few washes the shirt shrunk 15% and the buttons wouldn't hold in the button holes any longer. Plus the button down part of your shirt goes 2-3 inches further than "normal" polos do, so your middle chest shows like a porn star.

Stick with other people's brands and you're good
