Serena Williams Hits Grand Slam w/Nail Polish Ms. Bels Monday, January 10, 2011 Power Moves, The Runway, Trendsetters Serena Williams has always professed her love for nails. She even obtained a license as a nail tech in the state of Florida. So it made sense that she’d partner with a major nail polish manufacturer, OPI.

The collection is based off of several tennis opens: Australian Open, French Open (May 2011), Wimbledon (June 2011), and US Open (August 2011). To purchase, go to your local beauty supply store.
