Sizes: The size chart is based exactly on the t-shirt that was sent to me. Still, I don't feel like it's a very fitted cut, just tapered/fitted. Stretch: collar, shoulders slightly stretched. , and all over the chest The quality of the material and the seams: Absolutely flawless. This shirt has to withstand heavy loads for quite a long time. Color: The shade of blue is exactly the same as the stock photos. Overall: I like this shirt about as much as my tailored shirts. It's very well made and I love the fit. 5 Stars
