Serena Williams made a notable return to the US Open, attending the tournament on Saturday while donning a nostalgic denim skirt reminiscent of her 2004 style. This marks her first visit to the event since her retirement match in 2022, where she reached the third round. Williams, a 23-time Grand Slam champion, has kept busy with various ventures, including a book deal and a documentary series, since stepping away from professional tennis. She watched matches from a suite, including a straight-set victory by Jannik Sinner, and mingled with current players like world No. 1 Iga Swiatek. Williams' iconic denim skirt was inspired by Andre Agassi's fashion from the late 80s, with her original outfit debuting during her 2004 run at the US Open. Throughout her career, she has won six US Open titles and holds records for most finals and the longest gap between her first and last titles.
