Charlotte Olympia

White is an undeniably crisp Spring color, and when you throw white on top of white? Well, it makes for a double dose of freshness. Case in point: Lily Aldridge's latest NYC ensemble, which included Equipment's silky white button-down ($208) and these 3.1 Phillip Lim draped trousers ($375). Equally impressive were the model's add-ons: these adorable Charlotte Olympia kitty cat loafers ($825), Givenchy's black Pandora bag ($2,020), and cat-eye sunglasses. Score Lily's exact pieces below — but first, a few tips on perfecting white on white for day and night. Be sure to also check out more impeccable model street style here.

• Pick the white pieces that feel the most comfortable for you — it can be tees, tanks, jeans, skirts, shorts, etc.
• Like Lily, add nonwhite accessories for contrast. We especially love the mix of white with animal print.
• For an office-appropriate white-on-white look, try tucking a white silky blouse into a white pencil skirt, then finishing off with nude or black pumps.
• To make white work for night, add sexier details like strappy sandals and shiny jewels to dress it up.

While taking a break from New York Fashion Week to grab a bite at Bar Pitti, Jessica Hart covered her blond locks in NYFW's hottest hat trend — beanies! These toppers are clearly having a major runway moment — just check out BCBG Max Azria's Fall 2013 show — so take note from the Australian model on how to wear one too. Jessica completed her cold-weather ensemble with a white button-down, topped with a soft-pink ribbed sweater, black leather pants, Charlotte Olympia platform booties, and a black structured Salvatore Ferragamo bag.

Emmy Rossum attended the screening of Beautiful Creatures in NYC last night wearing a beautiful navy dress, black strappy Charlotte Olympia sandals, and colorful drop earrings, but it was the geometric-print Nonoo coat she sported on her way inside that really made an impression. We've been seeing a lot of amazing printed outerwear lately, and Emmy's look reminded us how a single piece of clothing can elevate an entire ensemble. Plus, the actress's satin pick is a seasonal-transition staple, working well from one season to the next. Layer up with sweaters and pants now; dresses and skirts later. Thus, we set out to find equally stunning Spring coats that will add the perfect mix of textural intrigue, color, and dynamic to the rest of your outfit.
