For an effortlessly stylish outfit, wear a blue turtleneck with violet plaid dress pants — these two items play really well together. If you want to easily class up this ensemble with a pair of shoes, why not complete your ensemble with a pair of black suede tassel loafers? Keep this getup in your front hall wardrobe when spring comes, and we promise you'll save a lot of time racking your brain for an outfit on more than one morning. This pairing is the perfect answer to the question of how to dress age-appropriately well into your 30s.
