Hold up. So you think any time pants are worn below the navel (even if just below), they look bad, even if the man has no extra midsection padding?Respectfully disagree on the bold text. If the thinner men wear the pants on the hip and below their navels, like some thin people who actually do that, it would look bad whether they are thin or not.
Wearing one pants at the correct position is very important, thin or not. For a thin men, if they wear the pants incorrectly, it still looks bad, but they do not have the belly to show. For men with a belly, it is more important to wear your pants at your waist, not below it, to not showing your belly too much. True, it could still show some of your belly, but at least not to exaggerate it by wearing the pants below the belly.
