Last night, Gucci celebrated the fifth anniversary of its campaign to benefit UNICEF with a private cocktail party and book signing by Michael Roberts at its flagship location. Claire Danes, Hugh Dancy and Grace Coddington were among those sipping and socializing with the author. Exclusively sold in Gucci stores, his "Snowman in Africa" book benefits the charity and provides a nice lighthearted balance against all that badass black leather. While everyone was dressed to the nines to honor the stylish shop, the writer also donned a Santa hat and beard to playfully fete the holiday season.
