The youthful diffusion line Sonia by Sonia Rykiel features just as much quirkiness and unconventionality as its older sister, but at more accessible price points. Popular clothing designs such as the side buckle jumper (fastened in front by an oversize zipper), body-con striped dresses in bright summery colors, stretch-cotton coats in electric blue, and patent leather handbags play with asymmetry and feature surprising details. Launched in 1990, Sonia by Sonia Rykiel is just one of several lines in Rykiel’s Paris-based clothing empire, which also includes Rykiel Woman, Rykiel Enfant for kids, a popular line of men’s clothing and accessories, and even an underwear collection for H&M. From leather shoes and handbags to color-block velour dresses to perfume and cosmetics, every design reflects Rykiel’s unconventional style.
