Roxanne Assoulin has nearly four decades of experience designing for brands including Marc Jacobs and Oscar de la Renta – but at 63 years old, it’s her cult jewelry line that’s making her the talk of today’s It girls. Intended to make people smile, the ‘Chiclet’-inspired pieces are crafted from colorful enamel tiles. Eva Chen, Leandra Medine and Karlie Kloss are fans of the bracelets and chokers.
