This laid-back combo of a dark brown shearling jacket and a long sleeve shirt can only be described as incredibly sharp. A pair of beige suede chelsea boots will easily spruce up any getup. During winter, when warmth is essential, it can be easy to surrender to a less-than-stylish outfit. But this outfit is a striking illustration that you can actually stay snug and remain stylish during winter. The ability to sport combos like this is one of the advantages of heading into your 30s.
