I recently found out I had a contact allergy to nickel, which meant that I had to stop wearing most belts with a silver-coloured belt buckle. For anyone else with a similar problem, this is a great solution. The whole frame of the buckle is wrapped in leather, so none of the metal ever comes in contact with the wearer.

It does run a bit long, but the loose end can always be tucked into a belt loop or into the belt itself - that's another benefit of having such a stretchy belt. The materials and construction are sturdy, and the look is actually versatile enough to go with jeans or slacks.
