Jessica Alba, Olivia Wilde & Anna Wintour Get Gussied Up For Gucci (PHOTOS, POLL)

Jessica Alba, Olivia Wilde and Diane Kruger stepped out to French Vogue's dinner for Gucci Creative Director Frida Giannini and the fashion house's in-store cocktail on Tuesday night in Paris.

And although the three actresses looked seriously chic, we're kinda more interested in another trio of guests: American Vogue Editrice Anna Wintour, outgoing French Vogue Editor-in-Chief Carine Roitfeld and her successor Emmanuelle Alt.

What do you think they talked about? The future of the Parisian glossy? Hair care tips (the merits of a well-maintained bob vs. letting it all go)? Fun stories from the State Dinner?

Take a look and tell us who was best-dressed.
