But at the third cocktail party, Holly donned a dress that may ring a bell for eagle-eyed Bachie fans.
The black ballgown looks just like the one worn by last season's winner Irena Srbinovska at her first cocktail party where she met Locky Gilbert.
Even the detailing on the bodice is the same, though we presume there's a different lining underneath.
What do you reckon?
Jimmy's also spilled that his celeb crush is TV and radio star Carrie Bickmore, and we have to admit Holly bears a strong resemblance to The Project presenter.
What's more, trailers show the pair's sizzling chemistry on their first single date together when they went paddle-boarding with Jimmy's adorable border collie.
"My pick for winner," one fan commented on the official Bachelor Instagram's post about the date.
"She gets to hang out with him AND his dog. She's the real winner already," noted another.
Holly also has odds at 1.35 and 1.10 on Sportsbet and TAB, respectively, to win.
In yet another clue, at home towns Jimmy lingered on the street and went on to share an intimate moment with Holly for "one last goodbye".
"A very important aspect of home towns is the goodbye on the doorstep and Holly had an incredibly dramatic, romantic, doorstep moment and I'm really seeing the strands of love through their home town visit," mused Bachie alum Alisha Aitken-Radburn on her and Osher Günsberg's podcast, Cocktails and Roses.
"I think that they have the foundations of something very strong."
Whilst Holly has great odds to be Jimmy's number one, she admitted that she's scared of one thing.
"My biggest fear in this whole process is probably letting my guards down and getting heartbroken at the end but I think we're here now so let's just do it, let's go for it," she laughed during the premiere.
Guess we'll have to stay tuned to see how their love story pans out!
