This pairing of a navy blazer and navy and green plaid dress pants is a goofproof option when you need to look like a true connoisseur of men's fashion. When not sure as to the footwear, add a pair of navy suede tassel loafers to your outfit. Seeing as fall is in the air, this getup appears a viable choice for the time in between seasons. Wear this pairing to create a more conservative look as a 30-something man.
