Serena Williams debuted her Glam Slam! England collection with OPI nail polishes earlier this month, and now she's putting her new shades to work! During her Wimbledon match this week, the tennis superstar wore a combination of three new colors—the vivid purple Grape...Set...Match covered four of her nails, and she painted the remaining finger the sparkly metallic silver named Your Royal Shine-Ness. She then topped each nail off with the glittery top coat Servin’ Up Sparkle. The polishes are available in stores now for $14.50 per set of two.
