Apostate is correct to a degree. A 1.5" leather gun belt will fit fewer than a third of my slacks.apostate wrote:My experience is that a 1.5" gun belt will fit business casual pants (e.g. khakis, chinos) but not suit pants. However, belt loops vary so nothing is absolute.
Belt-looping is evidently less than an exact science with haberdashers.

If you wear off-the-rack dress slacks, I think you'll need at least one, good 1.25" gun belt.
