It was all about celebrating the long weekend and spending time in the sun for some of our fashionable favorites this week, and they shared their stylish photos through social media for us to pore over (and envy). Poppy Delevingne indulged in some pool time with Cat Deeley, and Margherita Missoni showed off her growing baby bump while hanging in Venice. Nicole Richie  showed us how to nail an all-white look for Summer, while Hilary Rhoda made a case for the crisp white blazer look — even in sweltering NYC heat. We also got a glimpse of the photo shoot life from Doutzen Kroes, Lily Aldridge, and Behati Prinsloo, who all shared snaps from set.
