I'm a nurse and plan to use it with a navy colored scrub top. I'm currently 317lbs. 5'10". Waist is 56 inches, chest 50 inches. I normally don't review anything but us big guys need a hand helping each other out cause you rarely see a review for how clothes fit. The belly is snug but what do you expect? I love it. Going to order 4 more. The things is, either you wear a pair of scrub pants around your expansive gut and have it fall down and pull it up all shift or you wear it beneath your gut and have your underwear or undershirt showing all the time as well as having to pulling it up. This Kim Jung Il suit solves the problem cause there is nothing to show and no belt to adjust. Yeah, I have to wear my scrub top over it making things hotter but I don't care. The hem is a little long but you really don't have to hem it provided you are close to my dimensions. Durability probably won't be an issue since I just get exposed to bodily fluids or contact or airborne diseases so I am giving it 5 stars. It is light weight and thick enough for medical work. I can't speak for heavy use like for plant engineers or mechanics. 5 stars for that too. I hope this helps.
