A custom-made Nike brand tennis dress, worn by Serena Williams while competing in the 2011 US Open semi-finals against Caroline Wozniacki.

Williams staged a remarkable Grand Slam run at the 2011 US Open, dominating the field despite being seeded 28th after missing nearly a year due to a severe foot injury and a life-threatening pulmonary embolism.

Her most commanding performance came in the semi-finals, where she utterly dismantled world No. 1 and top-seeded Caroline Wozniacki in a lopsided 6-2, 6-4 victory. Williams dictated the entire pace of the match with an aggressive net game, firing 11 aces and 34 total winners to completely overwhelm the Danish star's signature defensive hustle. Though Williams eventually fell to Samantha Stosur in a controversial final, her breathtaking semi-final masterclass against Wozniacki stood as definitive proof that she remained the most elite power in women's tennis.
