Looks great, comfortable to wear, love that the buttons are the same color as the shirt, easy to wash, appears to be durably made. Significantly exceeded expectations (I ordered 2 more). 4 stars instead of 5 because it’s possible to move your arms in a way that makes the shirt slightly tight in the bicep area, but that’s unnoticeable almost all of the time (and minor anyway). Note: even after a couple of wash - wear - wash cycles, there were creases along the same places as where the shirt was shipped; this was easily remedied by a quick iron on a low setting and I think reflects that it is quite resistant to wrinkles.
