InStyle's editorial guidelines Updated on September 27, 2017 Pin Share Tweet Email Photo: 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.

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.
