bought an apc wool/leather varsity (a la toj0) in size L and it's very slim.
pulled it out of the box and figured they must have sent the wrong size given how small it looked. got it on, and was like a second skin. pretty limited range of motion, but 'fit' with arms at my side--sleeves creep up my arms if I extend my arms otherwise. base of the jacket falls just above my jeans in front, and a bit over top in the back--low rise, for ref.
my gut instinct was that it was too small, but tried it on tonight and wondering if that's actually the case. pics below.
