A handful of hot-dressed celebs, including Jessica Alba and Olivia Wilde, took a break from Paris Haute Couture Fashion Week last night to honor Gucci's Frida Giannini (she's the creative director of the company...aka the head honcho) at a dinner hosted by former 'Vogue Paris' editor in chief Carine Roitfeld. It was a fashion love fest for sure, and these were the looks we fell for...
JESSICA ALBA: Jessica stole the spotlight in a sparkly silver Gucci dress with draping over one shoulder, which she wore with blush-colored heels and a metallic Gucci clutch.

GEMMA ARTERTON: Bond girl Gemma Arterton, chose a more casual ensemble, but the pocketed Gucci dress was none the less chic...especially with those AMAZING nude peep toes!
