That really depends on your budget. I think L.L.Bean has nice dress belts for the price. Or you could do what I’m going to do and wait until July to place an order with Narragansett Leathers.
If you’re budget’s higher, then just visit a few high-end department stores or clothing brands and find one that’s appealing.

Is there something special happening in July? For some reason I don’t consider Narragansett Leather belts to be dressy enough.
They’re not taking any orders right now until after the Fourth of July holiday. Hence the wait.
As for not being “dressy” enough, I suppose it’s all subjective. I don’t really like the super-shiny look of a lot of dress belts. I prefer a bit of a duller look on my leather, so I think their bridle leather looks pretty great and the prices are reasonable. I’m not a person who obsesses over getting the world’s most perfect shine out of his shoes — for me it’s a matter of just maintenance to help them last longer. So, kind of the same approach toward belts.
