Reach for a waistcoat and charcoal dress pants if you're aiming for a clean, dapper outfit. If you need to easily dress down this look with one single item, why not choose a pair of double monks? There's nothing like a killer outfit to brighten up a dreary fall day. As a guy in his 30s, you probably want to start dressing maturely. If that's the case, combinations like this are a winning option.
