We love the way this pairing of a dark brown plaid wool blazer and blue dress pants instantly makes any gent look dapper and polished. A pair of black leather tassel loafers looks right at home teamed with this ensemble. With rising temperatures come warmer days and more sunlight and the need for a easy and breezy getup just like this one. This look is most probably exactly what you've been looking for as a 30-something gentleman.
