The Top Parties Of New York Fashion Week Spring 2015

Why: Anything Rihanna attended this NYFW (or anytime, really) becomes a headlining event, but Fendi would have managed even if the star didn't grace their new boutique with her presence. Sarah Jessica Parker, Anna Wintour, and the Kaiser himself Karl Lagerfeld all celebrated the new Madison Avenue flagship, joining the biggest names in the NYC scene for an utterly chic affair. Nonetheless, eyes were still glued to RiRi who proved to be the perfect icing on the cake. Who was there: Guests included Rihanna, Sarah Jessica Parker, Jourdan Dunn, Rachel Feinstein and Leandra Medine, Karl Lagerfeld, Silvia Venturini Fendi, Pietro Beccari, Antonio Belloni, Anna Wintour, Brendan Fallis, Anya Ziourova, Atlanta de Cadenet, Chelsea Leyland, Coco Rocha, Derek Blasberg, Elisabeth von Thurn und Taxis, Elisabetta Beccari, Fe Fendi, Giovanna Battaglia, Glenda Bailey, Hailee Steinfeld, Hailey Baldwin, Hannah Bronfman, Martha Stewart, Mia Moretti, Michelle Harper, Naomi Campbell, Natalie Joos, Nina Garcia, Olivia Palermo, Petra Nemcova, Rachel Zoe, Rosario Dawson, Sofia Coppola, and Zoe Kravitz.
