They share the same DNA, why not the same underwear?

Influencer twin sisters Brigette and Danielle Pheloung, 27, appeared on the podcast Gals on the Go where they dished their dirty secrets about their hopefully clean lingerie.

The New York-based influencers, who focus on fitness, fashion and lifestyle content, boast hundreds of thousands of followers.

The identical duo was explaining how they “literally” share everything but the internet was divided on just how tight their twin bond is.

“Wait, you want to know something crazy?” Danielle said to the show’s hosts, Brooke Miccio and Danielle Carolan.

“I’m actually embarrassed to say this … We only have one bra.”

Brigette chimed in, “And we share underwear,” which her sister confirmed.

Danielle explained: “We only have one bra because we don’t wear bras, but whenever we need a bra, we’re like, wait … and we’re fighting over it.”

The hosts asked which sister was wearing the bra for the episode, but they clarified that they both had their respective girls strapped in for the “rare” occasion because they own a black bra and a nude bra that they share.

But the black bra is the more popular one, given that it goes with more outfits, so they said they “basically” have one bra.

The Pheloung sisters admitted that listeners likely think it’s “niche” and “weird as f***” for them to share underwear but revealed that they’ve been doing it since high school.

People took to the podcast’s TikTok page to weigh in on the lingerie-sharing — and many were not caring for it.

“My twin and I don’t even hug let alone share underwear,” one user commented. “No. Straight to jail.”

Another wrote, “I’m a twin and no. I get it but I could never.”

A third person added: “My twin and I would fist fight every day if we did this.”

However, the pair had a lot of support, particularly from other twins who admitted they do the same.

“Me and my twinny do the same exact thing,” one person said, while another shrugged, “Same DNA!!!”

The twins posted a TikTok in which they mock themselves as they appeared to fight over a bra because one was moving out of their apartment.

“How you guys expected us to act the second we decided we were moving away from each other,” the post was captioned.

Naturally, one fan asked but has yet to get a response: “Who gets the nude bra and who gets the black bra??”
