Earlier today, the Paris runways were captivated by the return of Derek Zoolander and Hansel, but yesterday evening, the fashionable night owls took to a trio of parties. Jennifer Fisher and Claire Distenfeld hosted a sumptuous dinner at Caviar Kaspia to celebrate their collaboration; their chic guests included Prabal Gurung, Juan Carlos Obando, and George Esquivel, along with girls about town Veronica Chou, Dianna Agron, and Leandra Medine. Meanwhile, Fendi had reason to toast its recent collaboration with Thierry Lasry over cocktails at the Avenue Montaigne flagship. Sprinkled in the crowd were Noomi Rapace, Kris Jenner, and a bevy of models including Izabel Goulart, Soo Joo Park, and Lindsey Wixson. Last but certainly not least, Sacai pulled out all the stops for its intimate dinner at Colette’s Water Bar. Chef Shinichi Sato created a festive menu, and the guests, including _Vogue’_s Sally Singer and Lynn Yaeger, Pierre Hardy, and Sacai’s own Chitose Abe, were discussing the soon-to-be released book by the brand, Sacai: A to Z. With Paris concluding later this week, it seems that the fashion flock will be taking the weekend to catch up on sleep, bien sûr.
