I just bought a KW polo in medium. I have some complaints: Why are the armholes 7 1/4" across, when on the site it says they are 6 3/4"? I know it's only a small difference, but why not publish correct information? A 15" neck fits well, but, because it is a soft fabric, I could have gone to the 14.5", I think. Like others have mentioned, KW calling this a slim fit is misinformation again; it's so baggy in the body/waist and arms--it's unreal! I am quite skinny, which, of course, is affecting the fit, but why call it slimmest of the slim, when it clearly isn't? (I'm gonna have, to take it to the seamstress.) What I love about the polo is the fabric, the collar, the fact that you can choose a neck size (relatively) and the buttons! I just wish it was tapered, and that KW put the actual sizes online. I haven't washed it yet, but I don't think it's gonna make a hell of a difference. I know it probably means 'to fit' a 38" chest--not literally--but my medium has inches (4-ish) of extra fabric, and I'm a 37" chest!
