Bests & Worsts Reviews from Amazon

I am 5'4" 150lb athletic build (read: big shoulders/small waist/big butt and legs) Giving this product 4/5 stars due to sizing. Per the reviews I ordered a size up from what I normally wear (small). When I put the shirt on it was HUGE. Swallowed me up! Normally, I have issues wearing smalls because the shoulders/back fit too tightly and I have no mobility. This shirt however had way too much room through the shoulders, arms, and straight through the waist buttoned up. I'm going to have to send it back for a small I think. Hope this review helps you in your size picking!
