Sonia Rykiel, who is celebrating 40 years in business with a runway blowout and party on Oct. 1 in Paris, has enlisted some high-profile fashion folk to help celebrate. Rumor has it Rykiel’s daughter, Nathalie, has asked a host of international designers, including Karl Lagerfeld, Donna Karan and Jean Paul Gaultier, to design an outfit in the spirit of Rykiel to pay homage to the sweater queen as part of her jubilee.
