Saturday's most stylish celebs weren't spotted on a red carpet, but rather, taking in the garden-party-inspired vibe, exciting polo match, and grassy green of the fifth annual Veuve Clicquot Polo Classic on NYC's Governors Island. It was a chic, sunny mix of wares, ranging from Coco Rocha's ladylike Dennis Basso frock and Padma Lakshmi's crisp white maxi dress to Poppy's flirty floral sheath and Zoe's edgier Theyskens' Theory ensemble. Standout style setter Olivia Palermo — who rocked her own cool take on silky layers — shared her three can't-live-without Summer essentials with us: "sunscreen, a sun hat, and my Paul Smith sunglasses." Translation? Cool-girl styling doesn't get much easier than that. Rachel Zoe, Minka Kelly, Hilary Rhoda, and Jessica Stam were just a handful of the other fashionable faces to hit up this weekend's Polo Classic, so keep clicking for the complete style recap.
