Leather Card Holder

Mustard Zip Round Card Holder, $16 

A slimmer wallet is ideal for more tailored pants like trousers and khakis. They aren't bulgy and promote a clean silhouette, and they're more comfortable to sit on than a thick-ass leather wallet. Consider copping one in this seasonally-appropriate color and cut down on carrying coupons and cards you don't really use, without sacrificing style.
