I am 6 feet tall and 220 lbs. This shirt fit me perfectly in the chest and shoulders. My only complaint is that it is so long! I like to wear polo shirts untucked. This shirt goes completely past my rear end. If I wore it with ordinary shorts, you probably wouldnt be able to see the shorts at all – completely hidden by the shirt. It needs to be 4 to 5 inches shorter in terms of length to suit me. I have many RL polo shirts, and this one is by far the longest. I dont understand why.

The shirt was not the fabric I believed it to be. It says Classic Fit but was made like the older versions, not the soft cotton like my others. I don’t understand how the labels are the same but a completely different shirt. Oh well, stuck with it now.
