Since Posh and Becks, I have been obsessed with sport-spectator style, led usually by the WAGs (wives and girlfriends of athletes) who take their significant others' game days as an opportunity to display their style while showing support for the sport. This year has really ushered in a modern era of new WAGs, including mega-celebrities like Taylor Swift, who is dating Kansas City Chiefs player Travis Kelce, and Alix Earle, who is dating Miami Dolphins player Braxton Berrios. With such high-profile women stepping into the WAG game, there is more focus on what they wear on game day.

While I was digging into new WAGs to follow, one from the tennis community caught my attention. Morgan Riddle—the girlfriend of high-ranking U.S. tennis player Taylor Fritz—has been making a splash in the tennis world as a strong supporter of the sport and for her exceptional courtside style. In 2023, The New York Times described her as "the most famous woman in men's tennis," and she has since expanded her sport résumé to Formula One, attending the recent Miami Grand Prix with Charlotte Tilbury. Tennis is one of those sports known for their spectator style and strong aesthetic, and with the tennis tour taking place at glamorous locations around the world, it's no surprise that the tennis WAGs are winning when it comes to sport-spectator style.

I attended the Miami Open recently, which was my first time watching a tennis match, and when planning my outfit, I thought, "Who better to tap than Riddle for tips on what to wear to a tennis match?" I wanted to know her favorite courtside fashion moments from previous matches.

I ended up meeting Riddle in Miami at this year's Miami Open. Riddle was wearing the most adorable Cult Gaia dress and clutch in a hue of green that felt extremely appropriate for a tennis match, topped off with white pumps. Cosplaying as a WAG with Riddle for the day turned out to be just as glamorous as you would think it was. I joined Riddle in the VIP box where she was viewing the men's finals. We chatted about our favorite spots in New York City, stories from the matches she's attended all over the world—including hosting Wimbledon's fashion series Wimbledon Threads, which she plans on hosting again this year—and, of course, our favorite tenniscore brands. Riddle also spilled five of her favorite looks from Wimbledon, the Geneva Open, the Indian Wells Open, the US Open, and the Australian Open.

Wimbledon 2023

"This was a classic Ralph Lauren look. Wimbledon's official colors are actually purple and green, but I've noticed people tend to lean toward white and green if they veer toward a themed color palette. Sometimes, I like to play hard into tenniscore with a sweater around the shoulders, and this seemed like the perfect opportunity to do it!"

"I bought this Helmut Lang maxi dress at Saks 5th Ave the day before the match. It was inspired by one of my favorite Kendall Jenner street style looks. I will say the knee-high boots on a 90-degree day sitting in a match was not the move."

"Miu Miu is one of my absolute favorite brands the last few years, so this was a full look by them! I've noticed during their shows the models wear tights/socks, so I styled this with sheer tights and pointed kitten heels."

"When I'm traveling, I love to wear local brands, especially in Australia where they have such an incredible selection of brands and labels. This top is Kookaï, and the skirt is Henne. The Australian Open is the most casual of the Grand Slams, but I noticed a lot more people have dressed up in the last two years, so I've embraced it."

"Geneva Open is a tiny, little tournament in Switzerland and one of the most charming on tour. I matched this outfit (jacket from Tularosa) to the aesthetic of the grounds, which are covered in these giant, enchanting flower bushes."
