Pharrell Williams is 44 years old, looks 25, and should probably be 100. Dude has been hanging around in the public consciousness for at least two decades, and has had a tangible effect on popular culture for almost as long. As one half of the production duo the Neptunes, Williams changed the sound of hip-hop, R&B, and pop (in that order) in the 2000s, and has continued to innovate with each new sonic pursuit ever since. The rapper-producer-singer-songwriter is a genius, but if the only thing he’s remembered for ends up being “Happy,” that’ll be enough, because “Happy” still bops.

Musical endeavors aside, Williams has also dipped his toes into other waters, including fashion. In 2014, the multihyphenate signed a long-term partnership with Adidas, which so far has spawned, most notably, the NMD sneakers in his globally conscious Human Race collection. And now Williams has unveiled the latest addition to his burgeoning brand: a line inspired by 1970s tennis stars.

Just in time for the U.S. Open, which kicked off August 22 and continues through September 10, Williams’ collection offers a 2017 twist on the—hmm, how do we put this nicely—endearingly corny cable knits, polos, shorts, knee socks and especially headbands favored by ‘70s court kings like John McEnroe and Björn Borg. The new line retains those golden-era titans’ bold, signature looks, but sprinkles in useful updates from the present, including Adidas’ patented ClimaCool technology.

German tennis star Angelique Kerber and Spain’s Garbiñe Muguruza have been rocking pieces from the collection during the Open, proving that retro, preppy style still works in sports today. Peep the collection—which also includes kicks, towels, bags, visors, and wristbands—at Adidas’s store now.
