Jackie 'O' Henderson ensures all eyes are on her slender frame in a $1,500 bustier dress as she joins Pip Edwards and Grace Tame at marie claire Women of the Year awards in Sydney

Jackie O Henderson ensured all eyes were on her as she led arrivals at marie claire's Women of the Year Awards on Wednesday.

The radio queen, 49, flaunted her slender frame in a black Max Mara bustier dress.

Jackie's gown, which is priced at $1,500, was midnight blue and highlighted the breakfast radio star's cleavage with a U-shaped design.

The co-host of The Kyle and Jackie O Show accessorised with a silver clutch, and a pair of studded black strappy heels.

Jackie was joined by close friend Pip Edwards , who stunned in a black off-the-shoulder number.

The P.E Nation co-founder's slim frame was accentuated by the form-fitting dress, which also featured a very high leg slit.

Grace Tame was also present, wearing a red knee-length shift dress that was stoned with sparkling details.

The activist and sexual assault survivor completed the look with black boots and wore her hair up in a tight bun.

Athletic lovebirds Cody Simpson and Emma McKeon also turned up looking chic.

Olympic swimmer Emma, 30, went for a classic black gown with plunging neckline, pairing the look with a diamond necklace and a strapped heel.

Meanwhile, boyfriend Cody went for a black and white suit, minus a tie with an unbuttoned shirt.

He completed his look with a pair of blue-tinged sunglasses.

Podcasting power duo Laura Byrne and Brittany Hockley were also in attendance, and decided to have some fun on the red carpet.

Brittany wore a slinky black number, while Laura went for a sky blue dress, as the Life Uncut podcast hosts played around and laughed with each other in front of the cameras.

Real Housewives of Sydney star Sally Obermeder was all smiles as she went for an unconventional 'half and half' look.

The top half suggested businesswoman with a black, executive-style blazer, while the bottom half was a black sheer skirt.

Former Miss Universe Australia Jesinta Franklin also went for a business-inspired look, wearing an oversized jacket complete with pocket square.

Former Biggest Loser trainer Michelle Bridges also turned heads with a light blue satin number that hugged her fit figure.

The marie claire Women of the Year Awards are intended to 'acknowledge and celebrate the women who've been doing us proud this year'.

The glittering ceremony is presented by Swarovski, and will see women recognised for their achievements across multiple categories such as 'the Powerhouse,' 'the Creative' and 'the Changemaker.'
