Inside the society summit! Who's Who of the eastern suburbs doll up for posh ladies' lunch with a 'puzzling' dress code you'll never guess from the photos... as one arrival stands out like a sore thumb

A Who’s Who of Sydney’s eastern suburbs joined forces for the ultimate ladies’ lunch on Thursday as they descended on Coogee hotspot Mimi’s for a ritzy fundraiser.

Model sisters Simone and Madeline Holtznagel led the A-list arrivals – including reality stars, WAGs and doyennes of high society – as they dolled up to raise money for the Royal Hospital for Women.

Among the crowds was Bondi’s ‘Pilates queen’ Bernadette Fahey – the wife of Buildcorp COO Jordan Sukkar – who our sources say has been keeping a low profile lately.

There was also PR ‘It’ girl Montarna McDonald, Real Housewives of Sydney icon Terry Biviano, and Aussie Home Loans heiress Deborah Symond O’Neil.

Poppy O’Neil – the wife of billionaire freight heir Anthony Tzaneros – also made an appearance at what insiders are already dubbing ‘the society summit’.

A society source described some of the outfits as ‘puzzling’ given the theme was meant to be the 1950s. We’ll leave it up to you to decide if the ladies nailed the brief.

Fronting the pack were the Holtznagels, who looked a million bucks in show-stopping designer ensembles.

Proving glamour runs in their family, the sisters posed arm-in-arm upon their arrival, looking every inch the Sydney royalty they are.

Simone, 32, opted for classic sophistication in a $500 strapless black midi dress by Effie Kats that featured cut-out details and a timeless silhouette.

Madeline, 28, who welcomed son Jaeger with Merivale CEO Justin Hemmes on June 1, offered the first glimpse of her post-baby figure at the lunch.

She looked breathtaking in a sequined rose-gold gown with intricate beadwork across the bodice and a plunging neckline.

Publicity powerhouse Montarna, founder of The Audience Agency, also cut a stylish figure in a strapless white dress.

She arrived alongside Bernadette, the brains behind buzzy eastern suburbs Pilates and manifestation studio Body by Berner, who dazzled in a Magda Butrym design.

Terry, wife of NRL hero Anthony Minichiello, looked fabulous at 50 in a red designer dress, which she paired with matching pumps and a Lady Dior leather handbag.  

Meanwhile, socialite queen bee Deborah – the daughter of financier ‘Aussie John’ Symond and wife of Addenbrooke director Ned O’Neil – looked stunning in a pink maxi dress by Turkish designer İlkyaz Özel.

The blush-toned creation featured a chic off-the-shoulder neckline and sleek column silhouette.

Interior designer Poppy also proved that classic never goes out of style as she turned heads in a red strapless gown.

The brunette looked divine in the figure-hugging scarlet number, which featured a sleek bandeau neckline and daring thigh split. 

She was joined by society swan Lou O’Neil – the ‘brush heiress’ daughter of late Hayco founder Donald Hay and wife of property developer Jake O’Neil (Ned’s brother).

Lou, who announced in June that she and Jake were expecting their second child – opted for ethereal elegance in a flowing, cream-coloured gown.

Adjacent to the glamour, our photographer spied one familiar face who stood out like a sore thumb: 2GB breakfast host – and the event’s MC – Ben Fordham.

The sight of the sombre-looking journalist known for firing up on AM radio amidst a sea of impeccably dressed, air-kissing socialites was rather amusing.

As the afternoon sun began to set over the Coogee coastline, one thing was clear – the worthy cause had some seriously stylish supporters rallying for it.

The successful event was a perfect reminder that in Sydney’s eastern suburbs, supporting charity has never looked so chic.
