After serving up two OPI nail polish collections, Serena Williams is back in the game, adding three brand new lacquers with her Glam Slam England set! The line celebrates England's Wimbledon tournament, and includes the vivid purple Grape...Set...Match, the metallic pewter Your Royal ShineNess, and the glitter-packed Servin' Up Sparkle. "For stand-out nails, I love experimenting with different glitter shades," Williams said. "The new lacquers can be worn alone for a bright pop of color, or layered with Servin' Up Sparkle to create a textured effect." The Glam Slam England collection is in stores now, and sets of two sell for $14.50. Click through the gallery to see the polishes!
