Monique Lhuillier

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.

Monique Lhuillier sent a collection of 15 dresses down the runway for her fall 2013 bridal collection full of clean shapes and beautiful fabrics. As she told editors, her inspiration was to fit the needs of every bride, “from City Hall to the altar, whether there are hundreds of guests or just two.” The result was a broad but streamlined range, complete with sleeves and strapless, colors and ivory, gowns, and minis. Those shorter hemlines also served a second function—showing off the designer’s beautiful bridal shoes collection. Yet, while she played with new silhouettes and materials, like jacquard, the dresses were still classic Lhuillier, as show-stopping ballgowns covered in lace and tulle stole the show.
