This sleek Alligator Belt by DeSanto ($450) might be a little on the pricey side, but it can make just about any pair of pants in your closet look magnitudes cooler. The Italy-made belt has a 1 3/8" width, silver-toned brass buckle, and is leather-lined. It's available in a slew of fun summer colors, including red, sand, yellow, orange and, our fav, bright green.
