Bests & Worsts Reviews from Amazon

This shirt is not over/under-sized. It's more about the expectations of the consumer. There are many Chinese-made shirts I've purchased which are legitimately 3 sizes smaller than advertised. This shirt varies only in the wearer's expectations. I'm 5'9" and 178 lbs (as of this review). I wear a Medium t-shirt most of the time, but a Large looks ok on me as well. Dress shirt is 17 or 17.5, 34/35 and coat size is 42 regular. If I wanted a "slim fit" to the shirt, I'd get a Medium. A Large fits more baggy -- Closer to the advertised photo of the guy with his sleeves rolled up. An XL is really roomy around the waist and is much too big on me. I bought all three to try them out.
