Fit of short sleeve blues shirt

[cadetesman]

Just wondering about how the short sleeve blues shirt should fit, read 39-1 and couldn't find anything....my shirt has a tight fit, with the sleeves decently tight above the elbow. I have a really slender build, so basically all the other shirts are far too big..,so can anyone fill me in on this?

USAF shirts are what is referred to as a "tapered cut", so for all but the most "just out of BMT-fit" of us, the suggestion is to order
at least one size larger than normally indicated in a civilian cut.
