For an outfit that's very simple but can be smartened up or dressed down in a ton of different ways, try teaming a beige suit with a brown hoodie. Add a pair of black leather loafers to the mix to instantly change up the ensemble. So if you're looking for a look that's seriously stylish but also entirely spring-friendly, this one fits the bill. Pay attention to looks like this if you're on a mission to add seriousness to your 20-year-old's style.
