If it’s September, you can be pretty sure of two things: Serena Williams will compete at the U.S. Tennis Open after which she will make an appearance at New York’s Fashion Week.

Williams, who won her 6th U.S Open title and 18th Grand Slam single last weekend, has  fans on and off the court. One of the most recognized names in sports and renowned for a fashion sensibility that is both fun and flirty, Williams sported a pink leopard print dress during the day followed by a black leopard dress at night. Nike calls it “the fierce Nike Serena Dress.”

The sporty style displayed Tuesday at Fashion Rocks in Brooklyn, showed Williams’ perfectly toned bod in a leather crop top and matching flared skirt, punctuated with mesh open-toe booties.

The Grand Slam champion showed off her namesake collection of more than 25 looks — some in leopard and camouflage prints — on the runway that featured “easy fitting, yet bold, edgy and contemporary silhouettes,” including soft knits. The show was bold, confident chic with a touch of edgy street style. Prices range from $29.90 to $79.90.

What other athletes are showing some style?

Maggie Vessey hasn’t yet made it to the Olympics, nor become a household name. But the 32-year-old 800-meter champ from California, has a very real shot at becoming a fashion-world favorite.  Vessey debuted personalized, eye-popping outfits at track meets throughout the year, transforming the oval into a high-speed runway.  In a Runners World interview, Vessey explains that when her relationship with former backer New Balance ended in January, she resolved to take advantage of her newly blank slate and build a brand that truly reflected her.

Kara Goucher, Lauren Fleshman and other elite athletes showcased women’s running apparel brand Oiselle. Back at NYFW for the second year in a row, Oiselle founder Sally Bergesen said

“We’re really trying to move in a direction that shows how style and athletics work together beautifully and they can and should be together” .

Bobsled pilot Jazmine Fenlator and hockey goalie Brianne McLaughlin didn’t walk the runway, but they attended the Cute Curcuit show as VIPs.

For New York Liberty’s Cappie Pondexter, her many Fashion Week activities included a viewing of the 5:31 Jerome – Presentation, Harlem’s Fashion Row 7th Annual Fashion Show and Style Awards, and a front row seat to Williams’ HSN show.

Gymnast Nastia Liukin, a regular at New York Fashion Week, was part of the Project SUBWAY presentation judging the freshest looks and Olympic figure skater Sasha Cohen appeared on the runway for Subway’s Red Dress Fashion Show rocking a gold medal-winning Marc Bouwer gown.
