Gabbriette married Matty Healy in a Matières Fécales wedding dress with torn details

Only Gabbriette Bechtel could walk down the aisle in tattered couture.

The model and musician, 28, married 1975 frontman Matty Healy at Castillo del Lago, Madonna’s former estate in Los Angeles, on July 18.

The bride wore three looks through the course of the wedding weekend — all designed by buzzy high-fashion brand Matières Fécales, fresh off dressing Zendaya for her “The Odyssey” press tour.

Marking the first-ever bridal commission for the house, whose name translates to “fecal matter” in French, Gabbriette’s drop-waist white silk taffeta gown featured a hand-pleated bodice and triple bustle with train. The edges of the fabric were embellished with the brand’s signature “déchiré” (French for “torn”) technique, lending a deliberately ragged appearance.

She added a veil by legendary milliner Stephen Jones — pinned under her half-up, Lydia Deetz-like beehive hairstyle — and white satin curved-heel pumps from Matières Fécales’ collaboration with Christian Louboutin.

Canadian designers Hannah Rose Dalton and Steven Raj Bhaskaran were also behind Gabbriette’s “something old”: a black gown built using a vintage Martin Margiela dress that the bride already owned, according to Vogue.

It was “loosely inspired” by the trio’s love of Francis Ford Coppola’s “Bram Stoker’s Dracula” and was worn as a pre-wedding look.

“Is bridal always white? Clearly not,” Gabbriette told Vogue. “Bridal is whatever you want it to be. I’ve always been a fan of black clothing, and it felt right using this dress that I’ve loved for so long and repurposing it.”

For the after-party, the social media star changed into a two-piece lamb leather suit with fur and the same déchiré tulle at the sleeve and pant hems.

She accessorized with a white satin riding hat created in collaboration with Stephen Jones, plus another pair of Christian Louboutin x Matières Fécales pumps.

Her trio of looks were whittled down from 30 options presented by the designers, and took more than four months to craft.

Gabbriette’s long favored deconstructed fashion; for her bachelorette party last month, she wore a vintage Chanel tweed skirt suit made to look like it was coming undone at the hems.

And Healy proposed after one year of dating not with a traditional sparkler, but rather a black diamond ring. The center stone is surrounded by a halo of white diamonds, with experts telling Page Six Style the dark gems “symbolize power, elegance, mystery and strength.”

While black diamonds are not excessively valuable, they are extremely rare.

“Additionally, black diamonds can represent personal transformation, strength, and grounding,” one expert told us. “Many fans have pointed out that Matty seems like a new man with Gabbriette being around, tying in the meaning of transformation and grounding.”

Now, she’s the one experiencing a transformation — into Mrs. Matty Healy.
