Inside Nadia Fairfax’s Crazy 33rd Birthday Party

She is known as Sydney’s “it girl” of fashion.

It’s no wonder socialite Nadia Fairfax-Wayne went all out to celebrate her 33rd birthday this past weekend.

Held at the trendy Four Pillars Gin Lab in Surry Hills, Nadia’s birthday bash featured an array of unique details, including a strict blue dress code.

Nadia stunned in a royal blue mini dress covered in rhinestone tassels, which was custom made for the birthday girl by Australian designer Kourh.

She completed her look with a pair of strappy pink stilettos and a $3,000 rhinestone-encrusted Prada handbag.

Sharing details of her outfit on Instagram last week, the blonde wrote: “I have a blue house with a blue window. Blue is the color of everything I wear” – a reference to the iconic song by Eiffel 65 I’m Blue.

“Thank you for making my dream birthday dress,” she added, quoting designer Kourh.

Perhaps the most unusual element of the event was a large cut-out cardboard illustration of Nadia sitting in a tall martini glass.

The bespoke drawn artwork was created by Sydney illustrator Chloe Hoffmann, who also designed Nadia’s bespoke cocktail menu for the night.

The menu included a drink with a playful name called ‘Tanlines’ – perhaps a reference to Nadia’s love of Sydney’s eastern beaches.

Nadia’s circle of high-society friends were all in attendance, including fashion PR specialist Montarna Pitt and celebrity stylist Elliot Garnaut.

Fisher and Fairfax were once united at the hip, but the couple appear to have severed ties following Fisher’s recent cocaine scandal.

Fisher was reportedly caught buying cocaine on July 17, after her drug dealer was arrested by police for erratic driving in Bondi.

The cocaine drama went unnoticed by the media for months, before suddenly making headlines in September.

Fisher, 36, and Fairfax unfollowed on Instagram around this time, but it’s unclear why.

When Daily Mail Australia contacted the women for comment in September, they quietly re-followed each other on the social media app.

At the time, Fairfax also insisted that she had not fallen out with Fisher – despite rumors that their breakup was the talk of the Eastern Suburbs.

“What you are speculating is factually incorrect,” she said.

“Kristin and I have had a wonderful friendship over the years and I continue to wish her well throughout her current situation, and you will no doubt hear the same from Kristin.

“I had no prior knowledge of the [cocaine] incident, and discovered it like everyone else through the media.

In March, months before the cocaine scandal broke, Fisher served as bridesmaid at Fairfax’s multimillion-dollar wedding to financier Michael Wayne.
