For an effortlessly neat outfit, make a navy waistcoat and a crew-neck t-shirt your outfit choice — these two pieces work beautifully together. For times when this getup looks all-too-perfect, dial it down by slipping into a pair of white canvas low top sneakers. So if you're after a neat look that transitions easily into spring, this just might be it. An amazing example if you want to lose your boyish look and start dressing like an adult man.
