This off-duty pairing of a white crew-neck t-shirt and a navy crew-neck t-shirt couldn't possibly come across as anything other than seriously stylish. Finishing off with a pair of black leather loafers is an effective way to give a touch of sophistication to this look. On not-so-bone-chilling afternoons, rock this transitional ensemble and look absolutely awesome. Wondering what to wear as you step into your 50s? This getup is a wonderful example.
