Stella McCartney celebrated the opening of her New York flagship store in Soho by inviting some of her closest pals to a private dinner, including Naomi Watts and Saturday Night Live star Kristen Wiig (dressed in the designer’s clothes, of course). McCartney, an avid animal rights activist, offered a meat-free menu created by star chef Mario Batali to her guest list, which also included Liv Tyler, Stephanie Seymour, and Seth Meyers.
