You know that fun personality-gauging question, "If you could have dinner with anyone in the world, who would it be?" Well, the picks of any fashion-obsessed person were pretty much all gathered last night at an intimate dinner party hosted by Lauren Santo Domingo. 

The stylish socialite and founder of Moda Operandi kicked off Fashion Week and toasted to the website's new look at her fabulous Gramercy Park home alongside the likes of Mary-Kate Olsen, Diane von Furstenberg, Giovanna Battaglia, Sienna Miller, Tabitha Simmons, and Tory Burch. Always one to have a little fun, Santo Domingo waved away a stuffy sit-down affair in favor of passed bites and lively socializing. A highlight of the night (and a party trick we're likely to steal)? Caviar served out of porcelain potato skins.
