Layering a retro track jacket under your blazer may be a bit tired, but the idea of mixing sport and prep was an undercurrent we couldn't help but notice at several shows. Whether it was (1) bulky anorak collars at Duckie Brown or the (2) loose nylon layers at Z Zegna, the look is far better suited for fall. The best way of incorporating a bit of fresh-off-the-field machismo? Zip up a (3) fitted windbreaker under a jacket (seen at Michael Bastian) or over a (4) favorite cardigan (like at DKNY). Sure it'll keep you warm, but aren't you really doing it to look cool?
