This year, Holly Kingston and Brooke Cleal are in the running to win Bachelor Jimmy Nicholson's heart.
In a short teaser for tonight's episode, fans got a glimpse of the finale frocks. From what we can see, Holly is donning a yellow, white, and brown number, while Brooke has opted for a pink and purple ensemble.
The colour scheme is oddly familiar to last year's finale, where Irena wore a brown number and Bella donned a dark purple frock.
So if history is to repeat itself, Holly will land the pilot (just like Sportsbet predicts), and Brooke and Jimmy's love story will fail to take off.
This fan theory has been doing the rounds for several years now and has held true in all seasons but one.
Last year, it appeared Network Ten finally cottoned on to the fact they’ve been inadvertently leaking the winner each year.
As Bella Varelis and Irena Srbinovska fought for Survivor star Locky Gilbert’s affections, a spanner was thrown into the works when both women wore equally dark dresses (a ploy by producers to throw us off the scent?).
During the finale, Bella was decked out in a stunning plum-hued Georgia Young Couture ensemble, while Irena wore a two-toned brown dress by Con Ilio.
With part of Irena’s dress made up of the lighter brown shade, this seemingly suggested she would have the edge over Bella. And she did. The dress theory lived on!
In 2019, Chelsie McLeod wore a beautiful pale pink slip dress with light gold detailing on the bust, while Abbie was decked out in a sexy pewter halter-neck gown, meaning it was Chelsie who had captured astrophysicist Matt Agnew's heart.
While the Honey Badger picked no one and therefore ruled himself ineligible, fans were convinced Brittany Hockley had the upper hand over her love rival Sophie Tieman, thanks her white ensembles versus Sophie's cream-coloured outfit.
In 2017, Laura Byrne won the heart of Matty J, but not before she stepped out in a white frock during the finale.
Unlucky-in-love Elise Stacey wore the darker shade of gold, and then went home broken-hearted.
The year prior was Richie Strahan's season and in the official final two promotional shot, Alex Nation hinted at her eventual victory by wearing a stunning light gold gown.
This was in stark contrast to runner-up Nikki Gogan who donned a vibrant red lace dress.
Proving that the theory does in fact have a leg to stand on was Sam Wood's season in 2015.
The women vying for his heart in the finale were Snezana Markoski (dressed in a beaded white dress) and Lana Jeavons-Fellows (wearing a slightly darker baby blue frock).
Again, it was the lighter hue and its wearer – aka Snez – who left the finale triumphant.
Even in Blake Garvey's controversial season, the "dress theory" proved correct as Sam Frost was proposed to while wearing a sparkling silver dress, while runner-up Lisa Hyde was dumped in a plunging jet black gown.
The original Australian Bachelor, Tim Robards, also picked a winner that was predicted by an outfit.
Winner and Tim's now-wife Anna Heinrich wore a light-coloured beaded ensemble while rejected bachelorette Rochelle Emanuel-Smith left rose-less in a bright pink dress.
So, will the dress theory predict the future once again? We can't wait to find out!
