Olivia Palermo, a 27-year-old socialite who has garnered attention as a fashion icon since appearing on MTV's reality show "The City," is a real-life "Gossip Girl" who graduated from a prestigious New York school and is a major star in the social scene.

Her chic street style, which combines designer brands with fast fashion items, is always a hot topic, and at the recent Cannes Film Festival, she wore a Roberto Cavalli dress with an elegant train.

At the premiere of "The Immigrant" on May 24th, she wore a glamorous gold Cavalli gown. The jacket and her signature clutch bag were from ZARA. The yellow diamond bracelet and ring were from Avakian.

The night before, she wore a leopard print gown with her German model boyfriend Johannes Huebl to the amFAR (American Fund for AIDS Research) gala dinner hosted by Roberto Cavalli together with fashion director Carine Roitfeld. She looked classy in the revealing, sexy dress.

For this charity event, the brand provided the setting and spatial design for the venue using items from the Roberto Cavalli Home Collection, and Kylie Minogue and Sharon Stone also attended in Cavalli dresses.
