The U.S. Open is over, with a pair of new champions in New York City: first-time winner Coco Gauff and 24-time-Grand Slam champion Novak Djokovic. It was an exciting two weeks of tennis and fashion, as the celebrities who attended all brought their A game when it came to courtside style. There were bright colors, funky sunglasses, and matching sets. Here, 18 of the best dressed celebrities spotted at Arthur Ashe Stadium:

Emma Watson

Actress Emma Watson, who attended Wimbledon on multiple days this year, also made an appearance across the pond to watch some tennis. She kept it cool in a white suit, black vest, and slides by the Row.

Beach Slide in Leather

Amanda Seyfried and Rachel Brosnahan

Actresses Amanda Seyfried and Rachel Brosnahan both looked chic in sets from Ralph Lauren; Seyfried was in a pinstriped pant and top, while Brosnahan wore a denim vest and denim pants.

Cenza Pinstripe Cropped Blouse

Michelle Obama

Former first lady Michelle Obama was in attendance on the first night of the U.S. Open this year, to honor Billie Jean King and celebrate 50 years of equal pay at the Grand Slam tournament. She looked effortlessly chic in a denim Oscar de la Renta dress and Chloé sandals.

Sweetheart Neck Denim Dress

Camila Alves and Matthew McConaughey

Matching outfits for couples was clearly the move for this year's Open (see: the leather jackets worn by Hailey and Justin Bieber, or Kylie Jenner and Timothée Chalamet in all black), but the effortless swag of Matthew McConaughey and Camila Alves, in white suits and designer sneakers, makes it onto the best dressed list for us. They even sat in Novak Djokovic's player's box for his win.

Women's Screener Leather Sneaker

Yvonne Orji and Danai Gurira

Actresses Yvonne Orji and Danai Gurira kept cool in the New York City heatwave; Orji wore a Sandro knit set, while Gurira was in a silk Reformation dress.

Marguerite Silk Dress

Katie Holmes

Katie Holmes demonstrated that ballet flats work with practically any outfit—here, jeans and a tank—and tied a Miu Miu sweater around her shoulders.

Cashmere knit polo shirt

Justin Bieber and Hailey Bieber

The Biebers were spotted in Arthur Ashe Stadium (and yes, that's Jimmy Butler, NBA star and tennis fan, sitting behind them) cheering on Coco Gauff. They wore matching leather jackets, and Hailey accessorized with a "B" necklace and gold hoops. However the style highlight here is undeniably Justin's chunky Loewe sunglasses and polka dot baseball cap—two accessories that shouldn't work together, but absolutely do.

Inflated Cateye Sunglasses in Nylon

Nicole Kidman

Actress Nicole Kidman attended both the men's and women's finals, but our favorite outfit was this Self-Portrait midi dress and Freda Salvador penny loafers she wore to watch Coco Gauff's victory.

Petra Combo Penny Loafer

J Balvin

Colombian singer J Balvin wore two brightly colored monochrome outfits to the U.S. Open. For both instances, he wore a lightweight polo and fun sunglasses—it mirrored the vibrant energy of the New York City crowd.

Hopkins Extra Fine Crepe Cotton Knitted Polo

Charlize Theron

Actress Charlize Theron, the face of Dior's fragrance J'Adore, was in head-to-toe Dior for the women's finals. She paired the "Lucky Dior" t-shirt with a pleated skirt and chunky sandals, and carried the classic Dior Women's Book Tote.

Dioract Sandal

Laverne Cox

Laverne Cox showed the power of a statement blazer in this vintage Thierry Mugler look from his 1993 cruise collection, from her personal Mugler archive. She paired it with a black pencil skirt, and dangling pearl hoop earrings.

Cultured Freshwater Pearl Huggie Hoop Earrings

Laura Dern

Actress Laura Dern looked like she stepped right out of the 1970s in these flowing, wide-legged floral pants by Emilia Wickstead and ruffled white Chloé blouse.

Hullinie Trouser

Naomi Watts

Naomi Watts embraced the end of summer in an Ulla Johnson ruched midi dress and a Foundrae necklace.

Sister Hook 18-karat gold necklace

Taye Diggs

Men's fashion doesn't have to be boring, as Diggs demonstrated when he arrived at the U.S. Open in a printed Neuw Denim t-shirt and Nike shorts. It was a sporting event after all!
