Hello. These form fitting shirts were carefully tailored and the three shirts I received (navy blue/grey/black) had no fabric stretch, "flange" or seam defects. I'm a 5'11" male, about 170 lbs. and the Large fits snugly around my torso and armpits. While raglan sleeves have no seams to chafe at the top of the shoulders, I loved the tapered fit of shirts too tight around the shoulders and underarms. I've also found that the fabric in these shirts doesn't "breathe" nearly as well as (any) other sports shirts I own. The ability of shirts to absorb sweat , didn't allow me to stay cool even during regular workouts I felt clammy, I was covered in sweat that was slowly evaporating It was for me... Verdict: Those nice 'cheap' thin shirts are better for lounging than for exercising.
