Alessandra Ambrosio's Supermodel Status Shines at Dolce & Gabbana Show.

Alessandra Ambrosio stunned on the red carpet at the amfAR Gala at the Cannes Film Festival in a sheer, nude gown designed by Peter Dundas that hugged her curves with a plunging V-neckline and a thigh-high slit. The 42-year-old supermodel accessorized the chic ensemble with hoop earrings, a feather throw, and strappy sandals, looking like an old Hollywood movie star. Ambrosio advised anyone going to the festival for the first time to "try to be natural" and "just be yourself."
