Model risks a wardrobe malfunction in a racy flesh-baring dress at Glamour on the Grid ahead of the Formula 1 Grand Prix in Melbourne

Melbourne socialites donned their finery and headed to the Marriott Bonvoy Lounge in Albert Park for Glamor on the Grid on Wednesday night.

But it was model and beauty columnist Sarah Czarnuch who stole the show in a racy dress by luxury fashion designer Marquise Ateliér.

The blonde beauty wore an unconventional design, consisting of a long, silky skirt that hugged her figure and one of her arms, and a skimpy top that showed off a hint of underboob.

The cut of the dress also revealed Miss Tourism Australia 2014’s washboard abs.

Sarah completed her look with diamond earrings and bracelets that caught the light in the same way as her sparkly top.

Her makeup was a smooth bronzed style, with an accentuated eye and nude lipstick, while her platinum blonde tresses were worn down and styled over her shoulder.

In 2017, the model revealed her secret to a healthy lifestyle during racing season at Geelong Advertiser.

“I limit the amount of alcohol I drink. I just finished spring racing, so of course it’s not always practical, but it’s finding a balance.

“I noticed huge changes in my energy levels as well as my appearance, and even in things like my skin, hair and nails,” she added.

Sarah has over 127,000 followers on Instagram, where she posts beauty stories and updates about her lavish lifestyle.

She is also a Pilates instructor, influencer, and owns a design company called SarahCzarnuch x Elliatt.

She has been dating cricketer Marcus Stoinis for around three years now, and the couple often share photos on social media.

Stoinis was previously involved with TV presenter Stephanie Muller, but their relationship ended in 2021, around the time Marcus and Sarah started dating.
