For a look that's street-style-worthy and casually sleek, consider pairing a charcoal wool blazer with a navy crew-neck sweater. Beige canvas low top sneakers are the most effective way to bring a touch of stylish nonchalance to your getup. So if you're in search of a kick-ass look that transitions easily into spring, look no further. Rock this getup to pull together a more mature look as a 30-something gent.
