Nuala, Christy Turlington's yoga-inspired range of sportswear, is to add new lines and expand geographically after promising sales, WWD reported. Just one year after Ms Turlington launched Nuala, the line will add clothing that can be worm after working out, plus innerwear and outerwear. The brand will also open its own concept stores, to be located within Puma shops. The first opened at the end of June in San Francisco and others are due to open in Paris and New York's SoHo district in November.
