Pippa Middleton is keeping busy! Duchess Catherine's younger sister wore pieces from her favorite go-to labels like Zara, Prada and Alice by Temperley all over London this week. Then, she traded in her daytime looks for a floor-length floral Project D gown at last night's All Saints charity bash. See more of Pippa's latest outfits in the gallery!
