If I see light on both sides of black or any other color at the same time, I buy a dark blue shirt, thin. Cheap stitches don't last. The tight fit was just loose with measurements. This is 4xl. In a quality shirt from Duluth Trading, I wear a 2xl, that's a big difference, and Duluth shirts are loose. These shirts I just bought are polo or muscle shirts. Well, they were now trying to return to the quality products of well-known companies.
