On Sunday, the Fleabag star wore a custom-made suit designed by Ralph & Russo for the star-studded event, which featured geometric black and gold ribbon appliqué, Chantilly lace and a silk lapel.
But, instead of returning the outfit to the designer, or keeping it in her wardrobe, Waller-Bridge has decided to auction it off, with all proceeds going to charity.
The suit is currently available to purchase on eBay, with the starting bid standing at 77,000 Australian dollars (£40,000). The auction is set to end on 20 January.
The auction page states that the tuxedo was made to measure for the actor, but is close to a UK size 12 and has also been signed by Waller-Bridge.
“I'm very excited that this stunning, one of a kind, couture tuxedo created by Australian geniuses Ralph & Russo will continue it's journey by contributing to this urgent cause”, Waller-Bridge said in a statement.
“If money raised by its auction can help raise funds to fight the disaster in Australia, the future impact of this suit will be far greater than the luck it brought me and the Fleabag team at the Golden Globes last weekend.
“To add to its allure... I spent most of the night brushing it past and rubbing it up against all the sparkly people I could find. These threads are laced with legends!”
The writer and producer has decided to split the proceeds of the winning bid between three charities: the Australian Red Cross Disaster Relief & Recovery Fund, which will help Red Cross emergency teams, WIRES Wildlife Rescue Emergency Fund and Wildlife Victoria, which are both on the ground assisting in the rehabilitation and recovery of thousands of Australian wildlife.
In a statement, designers Ralph and Russo said they are “delighted” by Waller-Bridge’s decision to sell the suit.
“Being both from Australia originally and with much of our family still residents across the region, it is with a heavy heart that we watch and hear the news of the terrible fires currently engulfing such large areas of our homeland,” they said.
“With Australia remaining so close to our hearts, we are delighted to stand next to Phoebe to support relief efforts with this special auction.”
So far, the fires have claimed 24 lives and have destroyed more than 1,500 homes, ravaging through more than four million hectares of land.
Meanwhile, ecologists at the University of Sydney have estimated that around 480 million animals had been killed in the wildfires, including 8,000 koalas.
