Fits 6ft 1in 225 perfectly and size XL was perfect if your skinny guy chose Large. I bought XL and XXL just in case and will be returning 2XL. The large one can be a bit short if you are 6ft plus but overall great stuff and I have just ordered 4 other colors. I don't know if they shrink after washing or not, but fingers crossed they don't. Worn on a date tonight and have received many 5 star compliments so far.
