Take your menswear game to a new level by opting for a navy sweater vest and white chinos. Add a more informal twist to an otherwise dressy look by rounding off with a pair of black leather desert boots. So as you can see, it's a neat, not to mention spring-ready, outfit to keep in your transitional arsenal. As a 30-something gent, you probably want to start dressing more maturely. If that's the case, getups like this are ideal as inspo.
