I am 5'9" and 190 lbs. I wear a size 36 in Levis and ordered a size 36 in these.They look great and are nice pants, but definitely designed for skinnier guys. I am not fat, but I do have a little extra beer weight these days. The waist and legs fit fine, but the crotch area is really small. It bunched up my junk so bad it looked like I was trying to shoplift a pomegranate out of Whole Foods. .
