Star-Studded: The Best Parties This Week

David Atlan

Where does Bella Hadid find the energy to do so much, so often?

During New York Fashion Week, she hit the DJ booth at a party with Off-White designer Virgil Abloh, and this week, the 20-year-old model hit up Milan’s Bulgari Hotel to celebrate the accessories brand’s capsule collection with Nicholas Kirkwood.

Being that it’s Bulgari, it was a fabulous affair, and Hadid wore a body-hugging LBD as she confidently clutched onto her gold Serpenti bag. Models Jasmine Sanders (also a Bulgari ambassador, like Bella) were in attendance along with Lottie Moss (yes, Kate’s little sister) and Caroline Vreeland.

For a mid-week pick-me-up, Naomi Campbell dressed to the nines for the Swarovski Crystal Wonderland Party, where she dazzled in a floor-length black dress nearby Karlie Kloss and Jourdan Dunn. Ellie Goulding greeted fellow music star Liam Payne at Emporio Armani’s after-party, collectively making us wish we had booked a flight to Italy to join them.

Of course, award-winning actors had to celebrate their hard-earned Emmys on Sunday night, so Reese Witherspoon and Nicole Kidman raised a glass to their Big Little Lies wins at HBO’s after-party. There, Jessica Biel radiated in a gold dress. Really, look at her highlight!

To kick off Paris Fashion Week, Valentino Creative Director Pierpaolo Piccioli welcomed guests like Olivia Palermo to the city's Hotel Costes for a party in celebration of the fashion house's I Love Spike Pop-UP boutique and installation. As expected, the star of the night was the Valentino Garavani Rockstud Spike bag, created and sold just for the pop-up.
