Serena Williams’ fourth and final collection from her OPI Grand Slam collection has been released and she’s going out with a bang!

The final set is available in stores this month, just in time for the U.S. Open, and features two gorgeous colors: Love Is a Racket is a romantic, classic red with Old Hollywood flare and Pros and Bronze will add spice to your nails with its shimmering, pinkish metallic finish.  

They’re great colors alone, but Serena, who has an eye for fly nail designs, even suggests layering them up. “Whether worn alone or with Pros and Bronze layered over Love Is a Racket for a golden glow, these two shades have rich hues that are perfect for transitioning from summer to fall,” she says.

This year the tennis pro rolled out two lacquers tied to each of the four major tennis tournaments. Serena’s passion for nails has even led her to go to school to get a nail technician license.
