This pairing of a blue double breasted blazer and navy chinos is a winning option when you need to look casually sleek but have no extra time to dress up. And if you want to easily step up your outfit with a pair of shoes, why not complement this look with derby shoes? This combination isn't a hard one to achieve and it's summer-ready, which is more important when it's extremely hot outside. No doubt, a goofproof option if we're talking style for 30-something Millennial gents.
