How to wear a gun belt with a suit

A carry belt has two jobs in a suit. It has to hold a holster and gear without sagging, and it has to look like any other good belt. Both VICI belts are top-grain leather in two layers around a hidden spring-steel core, with a dress-ready finish, so they work with slacks and a blazer as well as with jeans.
Match the leather to your shoes
Wear Classic Black with black shoes and Rich Brown with brown shoes. The Marshal comes in both colors. The Sentinel comes in Classic Black.
Keep the buckle simple
The Marshal has a brushed stainless prong buckle engraved VICI, on Chicago screws. The Sentinel has a low-profile brushed steel plate buckle on a hidden ratchet track.
Let the jacket do the rest
The spring-steel core carries the weight on your hip all day without sagging or rolling. Wear the jacket as you would with any belt.
Size it for how you carry
- Outside the waistband, or without a holster: no need to size up.
- Inside the waistband, including appendix and small of back: size up one size, on either belt.
- The Marshal is your pant size minus 2, or the next size up for inside-the-waistband carry. The Sentinel is the range that holds your pant size, or one size up for inside-the-waistband carry (Small to Medium, Medium to Large, Large to X-Large).
The fit finder does the math for both belts.
