Wron Size Shipped Twice
Color: White, Size: Large
I ordered a large twice. 1st delivery was an XL, two sizes too large. The second reorder was an L, and fit like a medium. They can't get the order siz right.

Worth The Price
Size: Medium, Color: Black
Arrived on time with no issues. Quality was fine for the low price. I needed some summer shirts after losing weight and did not want to spend a lot. Solid purchase for the price, so I ordered several. Sixty-five pounds later, they served their purpose.
