Sonia Rykiel is well known for her distinctive Rive Gauche sophistication, which includes some renowned signature details including the unusual inside out stitching. Sonia By Sonia Rykiel was established as a diffusion to the main line in 1990 and is headed up by the designer's daughter. It has a youthful and fun aesthetic that channels the spirit of both mother and daughter, combining ultra chic Parisian irreverence and bold colors and prints. Graphic T-shirts, slogans and cute dresses are typical of the brand. The Sonia By Sonia Rykiel line includes a selection of heels, from metallic pink wedges through to moccasin and fur-lined heels.
