The combo of a black crew-neck sweater and white chinos makes this a cool casual ensemble. Our favorite of a countless number of ways to finish off this ensemble is a pair of white and red leather high top sneakers. So if you're searching for a look that's on-trend but also entirely spring-appropriate, this one fits the bill. Laid-back ensembles for 30-something Millennial gents aren't actually that hard, as you can see.
