There are no second chances for daredevil Nik Wallenda when he’s performing his life-threatening high-wire walks. Fortunately that’s not the case when it comes to his wedding.

In a sneak peek at Friday’s episode of Say Yes to the Dress, Wallenda and his wife Erendira are preparing to renew their vows after 15 years of marriage, and Erendira shares the inside story of their engagement.

“He proposed to me on a wire in front of 32,000 people,” she says.

Nik famously proposed to Erendira during a sold-out show in Montreal in 1999, but the fiancés “had no money for a wedding,” Erendira says, “so we went to the courthouse, and I didn’t even have a wedding dress. I had to borrow one from my mother-in-law.”

Her “something borrowed” doubled as her “something blue” – she wore a long, blue dress, with polka dots; Nik wore a grey suit. The couple now has three children: Yanni, Amadaos and Evita.

Much like her husband – who has crossed tightropes over Niagara Falls, the Grand Canyon and the Chicago skyline (blindfolded!) – eighth-generation acrobat and performer Erendira has been performing since she was a small child.

For her “I do” do-over, Erendira is enlisting the help of the Kleinfeld Bridal to get her outfitted for the couple’s dream ceremony.
