The collection was true to Parisian wear, with plenty of sequined berets, poufy skirts, ruffled dresses, hints of Moulin Rouge, and of course, lots of black and white.
After her collection was unveiled, Sonia's daughter Nathalie announced, "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."
Thirty more models came out in Sonia Rykiel looks designed by some of the biggest names in fashion, such as Karl Lagerfeld, Roberto Cavalli, Michael Kors, Diane von Furtsenberg, Jean Paul Gaultier, and Vivienne Westwood.
