For a smart ensemble, consider wearing a navy puffer jacket and a charcoal turtleneck — these two pieces play really well together. For something more on the casually edgy side to finish off your getup, introduce a pair of brown suede work boots to the equation. Keep this look in mind when spring arrives, and rest assured, you'll save a ton of time getting dressed on more than one occasion. This ensemble proves that as a 30-something Millennial gentleman, you have a wide range of outfit options.
