A seasoned wedding attendee might be familiar with the chore of deciding what to wear to another’s big day, but a recent photo appears to show six women unwittingly made the same unanimous decision by opting for the same exact dress — and no, they weren’t the wedding party bridesmaids. A woman pictured in the photo shared the astounding coincidence to Facebook in a post that has since gone viral.

Debbie Speranza was among the six women who selected the $160 Forever New lace ensemble sold by Portmans, the Daily Telegraph reported Tuesday, and later posted the image on the brand’s Facebook page. The six appeared at the Sydney, Australia, wedding of Julia Mammone, who described the incident as “friggin’ bloody hilarious.”

“You really should start a bridal registry so that your customers can [inquire] whether anyone else has purchased one of your dresses for the same event,” Speranza captioned the image. “[N]o we are NOT the bridesmaids just the guests.”

“I am laughing so hard at the moment....cannot believe how many likes (over 10,000) and comments (over 600) for my photo about the dresses at the wedding,” Speranza wrote Monday on her Facebook page. “[Forever New] you owe me a gift voucher for the advertisement.”

The image, originally posted Sunday, amassed nearly 50,000 “likes” by Wednesday and more than 11,000 comments.

“I’ve heard of two women, maybe three, wearing the same dress, but six? You couldn’t make it up,” Mammone told the Daily Telegraph. “At first there were a few dirty looks among the girls in the same dress who didn’t quite know whether to laugh it off or go home and get changed.”

Mammone noted that her bridesmaids spent double the cost of the dress on their Shona Joy ensembles, but even they found the coincidence “hilarious.” She added, “Some people think it’s a publicity stunt for Portmans. I’ve been waiting for this day for three years — why would I pimp my wedding out for them?”

As for Speranza, she wrote Tuesday that the viral fame has become “a tad overwhelming for all of us.”

“[A]s happy as we are that [it’s] given a lot of people a much needed laugh in these times, it's also gone way past what we expected,” she wrote. “So [thank you] to all of those that saw the lighter side and for your kind words and media requests but I'm sorry it has to stop now.”
