Occunomix LuxLset2BYl Classic Long Sleeve Wicking Birdseye High Visibility TS

Tired of companies each having a different idea of what the various sizes mean. I ordered a similar product in XL, but it hangs off me. At least I can wear that one though--these, just ONE size smaller, stretch tight over my oversized belly and make me feel nekkid. Which is no good at work. So now I have three of these and they're useless, but there's nothing technically wrong with them so I can't return them.
