The Sonia Rykiel brand is a family affair; heiress Nathalie Rykiel launched the label's little sister, 'Sonia by Sonia Rykiel', in 1999. Cleverly incorporating Rykiel's signature inside-out stitching technique and Parisian chic aesthetic, Sonia by Sonia Rykiel is a youthful and quirky selection. Rykiel opened her first boutique in Paris in 1968 and is internationally renowned as the 'Queen of Knits'. Sonia by Sonia Rykiel tops are bright and whimsical with a chic, laid-back appeal. Jumpers, shirts, sweaters and T-shirts are adorned with sequins, appliqués and statement motifs for an adaptable go-to look.
