For your reference, I'm 5'11, 165lbs, 15.5" biceps and 31" belt size. I ordered both the dark grey one with light grey cuffs with light grey "3" and the teal/blue one with the dark blue "3".

This fit very well around my arms and chest and little loose around my upper and lower waist. It's a very flattering shirt.

The material is very thin and the seams are double stitched but have loose thread ends that needed trimming upon arrival. I'll wash it in the machine and report back as to how it holds up.

Additonally, it took about a month to arrive after ordering and the tracking number still doesn't show that it's been delivered.

Finally, even though they fit as I expected, I ordered a "Medium" on Amazon but the tag reads "XL" on both shirts. It appears that "XL" in Asia is equivalent to "Medium" in the USA.

Hope this helps!
