Now I didn't expect it to make me look BUFF or skinny. I'm 6'0", 265 lbs. A bit fluffy in the middle. Waist 38 inches, belly is bigger. It was pretty easy to install with the clasps. Good idea from the manufacturer. What they did for me was this one Taking rolls and curves and just pushing them into a slightly thinner but better held position. This is like a women's sports bra. Just keeps things tighter to make them look smaller and move less. I bought XL, while wearing XL or XXL t-shirts.It was tight but that's how it should be.After about an hour of wearing it the first few times I got a little nauseous but the third time even after a few days my body got used to it on it and I could go outside with a great feeling.I suggest buying the same size as the t-shirt that almost fits the skin without being restrictive.There are only 2 reasons to lose a star. First of all it's comfort it's a fucking itchy and burning feeling which was mostly remedied by wearing a shirt underneath, but a shirt, vest, shirt makes the day warm. Second, I felt like he could use maybe 2 or 3 inches of length to smooth out the last bit of the belly crease. Otherwise great for the price.
