On the heels of the so-called Happy Slam, the Australian Open, comes the season's arguable Fashion Slam, the well-heeled Roland Garros. This major event in the City of Lights supplies sartorial delights in spades. Consider it much adieu about everything. And with that, here are the fashion aces of this year's tournament, those turning the terre battue war into wardrobe opportunities.

Sloane Stephens, Maria Sakkari and more sported black-and-white bee-themed looks from Nike. Stephens' two-piece set included a lovely lavender "swoosh" detail.

In a Nike kit unique to him, Juan Martin del Potro boasted the best men's look that the House of Swoosh delivered this year on clay. While the afore-noted women's Nike looks went B&W only, Delpo's 1970s color palette brought rich hues and elevated the pattern to luxe status.

In another collab with Louis Vuitton and Off-White's Virgil Abloh, Serena Williams wore French-language words including "queen," "champion," and "mother" on her haute sweature attire. And, as touted at Vogue and here on this site, it made for another crowning achievement in her decades-young closet. Was the warmup jacket functional? No, especially when she practiced her serve. But in her post-bodysuit, apres-faux-scandal fashion life, hers was the most hotly discussed look on file in France.

Men's Best: In Uniqlo, Kei Nishikori did everything with his kit that Roger Federer's fell short in accomplishing: It was instantly attractive, even aspirational. Its bright, complementary colors evoked 1990s goodness and came off fresh as his personality and razor-like backhand.
