Her bikini top was a complementary bandeau style and featured interesting detailing on either side.

She shielded her eyes from the warm sun with a pair of over-sized rounded sunglasses, and tied her long blonde locks in a messy, low-slung bun.  

The Australian model has been enjoying the festivities of the Cannes Film Festival with her sister Ashley.

Shine on like Jessica Hart in Miu Miu

Jessica Hart stunned at the Cannes amfAR event in a dazzling Miu Miu gown. The silver and gold dress features a plunging neckline, jewel encrusted waist belt and fishtail silhouette. The scale pattern and Jessica's blond locks are really screaming mermaid vibes, and we love it!

The model styled the look with a pendant necklace with a gold chain strap clutch bag. Usually gold and silver clash, but Miss Hart has reigned in the look so masterfully.

The two siblings stunned on the red carpet at Cannes on Thursday evening, as they attended AmfAR's 23rd Cinema Against AIDS Gala at Hotel du Cap-Eden-Roc.

Former Victoria's Secret model Jessica was the more daring out of the two, showing a lot of front in a plunging cream and gold gown that flaunted her cleavage.

She further drew attention to her decolletage by accessorising with a dazzling diamond necklace, while toting a small gold bag.

The five-foot-nine glamazon further boosted her height in a pair of stilettos hidden beneath the hem of her dazzling metallic dress.

Meanwhile sister Ashley also showed some skin in a sheer red gown with strategically placed beading to cover her modesty.

The 27-year-old slicked her hair back into a half-up, half-down 'do, and wore simple accessories, including her gold wedding band from husband Buck Palmer.
