The 12 most daring looks Serena Williams has worn to the US Open

The tennis icon also wore a yellow and white Puma dress in 1999 with black pinstripes down the side. On Monday, her four-year-old daughter Olympia wore her hair in a nearly identical style when her mom took the court for her first match of the 2022 US Open.

Williams competed in the US Open for the first time in 1998. She came out on top the next year and went on to win the American tournament again in 2002, 2008, 2012, 2013, and 2014.

The 23-time Grand Slam winner is considered one of the greatest athletes of all time and, along with her sister Venus, responsible for changing the face of women's tennis.

Williams became known throughout her career for her ability to mix activewear with street style.

Her denim mini featured neon stitching and plenty of pleats, and the full look was completed with a Nike sweatband and wristband that matched her top.

Williams' Nike tennis dress was similar to the studded top she wore to another match, but her elongated shoes really made the ensemble stand out.

As usual, Williams matched her sneakers to her Off-White x Nike lilac dress, which featured a floaty, layered skirt. Although it may have looked like she was playing in a one-shoulder silhouette, there was a panel of brown fabric on the other side that blended in beautifully with her skin tone.

The world-famous athlete wore pink and white from head to toe for the competition. She added some contrast with a leopard-print pattern on her dress and wristband.

Williams swapped the colors on her wristband and Nike dress, which made her ensemble stand out from a similar look she previously wore at the tournament. Her black timepiece also helped pull the outfit together.

The tennis GOAT exuded power and strength in the graphic look, which appeared to be made with a snake-print fabric. She also matched her sweatbands to her outfit, allowing her white watch to stand out as she raised her fist.

The white-and-pink Nike outfit Williams experimented with a new silhouette. She paired the mock-neck dress with pink sleeves and sneakers with neon details.

With a combo of red, black, gold, and copper, Williams served up drama for the New York City tournament. The metallic details of her dress were balanced with a red emblem on her right side, lending a dash of drama.

She finished the ensemble with white sneakers and hoop earrings.

The icon looked super cool when she mixed her neon orange dress with bright yellow accessories, but the best part of the outfit was the snake print all over her frock. She balanced it with a slightly lighter shade of orange underneath, which gave the look some depth.

The pink-and-black Puma dress was slightly sheer over her dark undergarments and featured a slit on the side. Williams also wore a star hairpin on the side of her ponytail.

Insider's Meredith Cash reported that the Nike ensemble was designed in collaboration with Williams to represent highlights from her career.

The black outfit was embedded with shimmering silver and gold crystals, while her skirt consisted of six layers to represent each singles title she's won at the Grand Slam. However, she shared in a post-match interview Monday that she took out four of the layers because the skirt was too heavy to compete in.

Her accessories also had tons of sparkle and sentimental touches. Williams' custom kicks featured her initials written in gold, a gold charm on the laces, and 400 hand-laid diamonds that spelled out the word "Queen."
