Team a blue vertical striped suit with a navy parka and you'll be the picture of manly refinement. Why not complete your outfit with a pair of black leather loafers for an added touch of style? Many people suppose that just because you need to get bundled up you have to sacrifice on style, but it's just not true, and this look is a shining example. On the lookout for outfit ideas for 40-year-old guys? This combination is pretty inspiring.
