First, out of the package I love this jersey, it is super well made, perfect quality. It is gorgeous. I will try to size up again and see if I can get it to fit, but overall this jerseys style is tight performance fitting (in my view).
I am 5'11 188lbs, 33 waist, 32 inseam, relatively fit, small belly, I could not get the L or XL to fit comfortably. I am using a Castelli XL, and found this to be just a little snugger in the shoulders and chest, just a little. I don't need two tighter style jerseys so I am going to try one more size up next time I am in the shop.
I rate this 5 stars because it is a beautiful jersey, they put a lot of thought into everything and it shows.
