This laid-back combination of a grey knit wool turtleneck and navy jeans is a fail-safe option when you need to look sharp in a flash. Clueless about how to finish off your look? Finish with dark brown leather casual boots to smarten it up. Picking out a neat combination can be a bit of a challenge on its own. Add subzero temps into the equation, and the whole thing becomes all the more difficult. Fear not, this here is your wintry inspo.
