Don’t worry, it’s not a spoiler. We found that out in the promo for last night’s episode.

There’s a Cinderella-slash-Year-10-formal moment when Keira descends a set of stairs wearing a strapless A-line gown, and meets Richie, who looks dashing in a tux.

This dress may look familiar to eagle-eyed Channel 10 viewers.

It’s by the same designer of this dress worn by Sam Frost on The Bachelorette and last year’s The Bachelor contestant Rachel Moore.

Australian couture designer Philippa Galasso says she has “lost track” of the number of dresses she had loaned to Channel 10 for both shows.

“Keira’s gown in tonight’s episode is straight from our New York Fashion Week runway show and the gown has not been modified or worn previously,” Ms Galasso told news.com.au.

“Being part of The Bachelor has been great publicity and exposure and it has been great working with the styling team at 10,” she said.

Her dresses don’t come cheap — Keira’s costs $6750 and the gown worn by Rachel and Sam cost $6230.

All of Ms Galasso’s gowns have been loaned to Channel 10 for free.
