Review on 👕 Medium Men's Clothing: Racerback Stringer Shirt in Pastel Yellow by David Thomley

I don't know why some reviewers are saying buy one size up. I have, and although I have a muscular build and always wear a medium or small, the medium fits very poorly - and has an odd fit. I weigh 160 pounds with a 42 inch chest and the average size is huge for me - more for a 48 inch chest. It's very wide and expands under the arms - I think you must have huge, flared armor to wear that.
