We love the way this smart pairing of a white crew-neck t-shirt and black dress pants immediately makes you look on-trend. To inject an easy-going vibe into this look, add black athletic shoes to this ensemble. Keep this getup ready to go when spring comes, and we guarantee you'll save a lot of time crafting an outfit on more than one morning. Combinations like this help welcome this next milestone that is your forties with class and confidence.
