Loving how this pairing of a grey wool blazer and a blue dress shirt instantly makes any guy look smart and refined. If you need to immediately tone down this ensemble with footwear, introduce white leather low top sneakers to the mix. So as you can see, it's an on-trend, not to mention spring-friendly, ensemble to keep in your seasonal rotation. Interested in fashion for 30-something gentlemen? This combination definitely goes to your inspiration folder.
