Layer Up With October's Most Coveted Fashion Must Haves

I'm addicted to art deco whatever the season, but as cozy knitwear and simple separates come out for the colder weather, there's never been a better time to invest in a serious statement piece, like the Kate Spade imperial tile necklace ($248). While it may be a bit much teamed with a busy dress, add it to a cashmere sweater or a simple turtleneck, and it lifts a look from boring to "Oh my God, where did you get that?"
