For a casually dapper ensemble, pair a black and white sweatshirt with a crew-neck t-shirt — these items fit beautifully together. On the fence about how to finish off? Complete this look with a pair of white athletic shoes for a more relaxed finish. This look is a safe option if you're looking for a great, season-appropriate look. Sartorial inspiration like this will help you remain enviously fashionable as you drift through your 20s.
