A blazer and a white and black crew-neck sweater combined together are a match made in heaven for gents who love casually smart styles. Tap into some David Gandy stylishness and introduce a pair of black suede loafers to the mix. So as you can see, this look is a really wonderful idea, especially for transitional weather, when the temps are dipping. This one is a nice and age-appropriate combo for a 50-year-old.
