Ahna O’Reilly made her first-ever Cannes Film Festival experience a memorable one! The actress has put on a full fashion show in the French Riviera, as she showed up to event after event in high-fashion looks. The latest we love: This Monique Lhuillier design, which she paired with Salvatore Ferragamo shoes, H. Stern earrings, and a Jennifer Behr headband—and she gave us the exclusive behind-the-scenes look at the process to get her red carpet-ready. “I felt amazing in the dress,” she told InStyle.com exclusively. “Ever since I put it on for the first time, I knew it was what I wanted to wear. Walking the red carpet in Cannes for the first time was surreal, and a total dream come true.” Click through the gallery for a closer look, and get details from her glam squad, including stylist Caley Lawson, hairstylist Kylee Heath, and makeup artist Kindra Mann on how they made her dream a reality.

Dior presented its 2014 resort collection in Monaco’s capitol of Monte Carlo over the weekend, and the stars attending the Cannes Film Festival in neighboring France briefly left the scene to take in the design house’s fashion show. Clad in head-to-toe Dior, Jessica Biel, Marion Cotillard, and Zhang Ziyi traveled the 50 minutes to Monaco to join Princess Charlene of Monaco to watch the Dior Cruise Collection make its way down the runway. Afterward, the stars stayed in Monaco to celebrate the sophisticated and feminine collection at a cocktail reception thrown by Princess Charlene in honor of her good friend and Dior designer, Raf Simons.
