Starter compression garments at Walmart

Thanks to all the guys *****commended the Starter compression garments. I picked up a LARGE short sleeve shirt and it holds things in. I have a 46 and a 48 suit coats that are exactly the same coat besides the size. The 46 was too tight to button and it was tight through the chest. Now it is a little big. I may have to look at a 44. The only complaint is the logo on the shirt.
