"A birthday without a surprise isn't a birthday. You've been inspiring the world of fashion for 40 years; here's your present. Bon anniversaire, Maman." Out came 30 more models in Sonia Rykiel looks designed by some of fashion's biggest names. Martin Margiela made a fur chubby the color of Rykiel's flame-red mane. Rodarte's sweater dress read "Obama." Jean Paul Gaultier's came attached to giant knitting needles and trailing a ball of yarn. Happy returns, indeed.
