"Say Yes to the Dress" will feature a throuple for the first time on Saturday.
Kleinfeld Bridal helps two members of the throuple find their dream wedding gowns in the episode.
Insider has an exclusive clip of the consultants finding out they're working with a throuple.
"Say Yes to the Dress" will feature its first throuple in the next episode of the series.
Saturday's episode follows the brides Carly and Kassandra as they search for wedding dresses.
They plan to celebrate their relationship with each other and their third partner, Paolo, in a ceremony next year, they say in the episode.
Ahead of the episode's premiere, TLC provided Insider with an exclusive clip in which the Kleinfeld Bridal consultants meet the trio.
As Insider's Canela López explained, the term "throuple" refers to a long-term romantic relationship between three people, and it is a form of polyamory.
"We obviously understand that this kind of dynamic is not for everyone, but we just hope that even if they don't understand that at least they can respect the relationship," Carly says in the clip.
"This is my husband, and this is my fiancée," Kassandra tells their consultants, Krissy and Candace.
The Kleinfeld staff members respond with "wow" in unison.
Kassandra adds that she didn't want to scare them with their nontraditional relationship, but Candace quickly reassures her.
"No one's scared. We're ready," she says. "It's 2021 - anything can happen."
The clip then shows Carly's, Kassandra's, and Paolo's parents explaining how they came to terms with their children's polyamory.
"In the beginning, it's hard to wrap your mind around it," Kassandra's mother, Eunice, says.
"I'm all there now, but it wasn't like that in the beginning," Carly's mom, Fanny, says. "I took it kind of rough for a good few years until I saw it with my own eyes and I realized this is true love."
"That's the avenue and the path we've taken. We're supporting our children regardless," Eunice says. "It's all about love."
The throuple says they cannot get legally married in their state, adding that the wedding will be just a celebration of their love with their friends and family.
While studies show people are becoming more accepting of nonmonogamous relationships, people who live publicly as polyamorous still have to grapple with social stigmas. Indeed, the throuple featured on "House Hunters" later told GQ they lost jobs and friends because of their relationship.
"Say Yes to the Dress" airs Saturday on TLC at 8 p.m. ET. You can catch up on the 19th season on Discovery+.
