Australian fitness influencer Kimberley Searle nearly suffered a wardrobe malfunction on Saturday when she arrived at Perth's Ascot Racecourse for Derby Day in a cut-out black gown.
The social media personality went braless in a figure-hugging $169 black maxi dress from Australian fashion brand Runaway The Label while attending the G.H. Mumm champagne tent.
Her maxi dress featured a plunging halter neckline, cut-outs, an open back and a thigh-high split. The figure-hugging design showcased her toned physique and bust, bringing her close to a major wardrobe malfunction during the race day event.

Runaway The Label dress and race day styling
Searle paired the black gown with contrasting white accessories. She carried a fluffy white handbag with a feather-like texture topped with a beaded pearl handle, and wore a pearl headband in her hair along with a pair of white strappy heels.
She completed the look with understated makeup that highlighted her complexion with a sun-kissed glow, defined eyes and a soft, natural lip. Posing against a floral backdrop, the influencer showed off the outfit from multiple angles, marking a departure from the more traditional race day attire seen at the track.

Ascot Racecourse, located near the Swan River in Perth, is the headquarters of thoroughbred horse racing in Western Australia and operates as the main summer and spring venue for Perth Racing. Derby Day is one of the marquee fixtures on the Australian horse racing calendar and is traditionally associated with black-and-white racewear. French champagne house G.H. Mumm is a long-standing sponsor of major Australian racing carnivals, hosting trackside hospitality marquees, while Australian label Runaway The Label specialises in women's occasion and evening wear.
Social media post and fitness career
Searle shared a gallery of photographs of the race day outfit on social media, where she has built an audience of thousands of followers.
"A moment for the dress," Searle wrote in the caption. "Make your body the best outfit you will ever wear."

The Australian creator has grown her online following through her focus on fitness and social media, regularly sharing glimpses of her lifestyle with her audience. Alongside her social media presence, Searle serves as the face of Melbourne activewear brand Elite-N-Titled.
