My everyday & dress belts are dress gunbelts: 2 by Ted Blocker in cowhide, & 1 by Greg Kramer in horsehide. They don't sag, no matter what's on them.
The Kramer in horsehide has been worn almost daily for 3 years; the only problem with it is some fading of the dye where the most wear is. The Blockers are older, & still look good (cowhide takes dye better than horsehide, so I'm told).
A good gunbelt will cost more than a regular belt, but will outlast it by years. It doesn't matter if you don't carry a gun: the belts are the best!
