For an ensemble that's pared-down but can be worn in a ton of different ways, choose a navy plaid wool blazer and charcoal skinny jeans. And if you wish to instantly ramp up your ensemble with shoes, introduce a pair of dark brown leather double monks to your outfit. So so as you can see, it's a sharp, not to mention spring-ready, outfit to have in your transeasonal rotation. Wondering how to perfect semi-casual dressing as you drift through your 20s? This combo is a good illustration.
