Olivia Palermo attended a screening of No Strings Attached in New York City looking not only chic, but totally cozy. She layered up with a leather dress, thick feathered vest, and sleek metallic leather jacket. She added black footless tights and suede booties for even more warmth, then accessorized with a colorful clutch and silk scarf. Her look is the perfect mix of effortless cool and downtown chic.

Who says a turtleneck has to be stuffy? Certainly not model Jessica Stam, whose cool chick turtleneck is proof that pulling off this wintery look is all in the styling. To keep things from becoming too bulky, just pick a lighter fabric, even sheer if you please. As for the rest of your ensemble, try a mini or tap shorts and tights, and if you're going to do denim, go skinny and sexy to keep up the cool vibe — customizable Prada shades are optional but always encouraged.

Besides her hot strut, we're eying Victoria Beckham because of her Fab little sheath. It's modern mod at its best — simple silhouette, rounded neckline, and no bells and whistles. It's all about the fit — not too body-conscious, not too billowy — it should have a body-skimming, ladylike fit. For extra flair, go with a retro palette; bold yellows, orange, blue, and the rest of the primaries are perfect. And also look to Mrs. Beckham for the right accoutrements: oversize sunnies and a pair of pretty pumps.
