Ariana Grande has a showgirl moment in vintage Bob Mackie for ‘Wicked: One Wonderful Night’

Ariana Grande didn’t need a bubble to float in — just a Bob Mackie.

The multi-hyphenate star, 32, wore a strapless gown from the legendary designer’s Fall/Winter 1997 collection for “Wicked: One Wonderful Night,” the NBC concert special celebrating the upcoming release of “Wicked: For Good.”

The champagne-colored confection had a fitted bejeweled bodice with a sweetheart neckline that flared into a voluminous tulle skirt, creating a silhouette worthy of Glinda the Good Witch herself.

She paired the archival treasure with a diamond choker and a sleek ballet bun, wrapping a coordinating champagne satin safety harness around her waist for her airborne entrance into the Dolby Theatre in Los Angeles.

Her gown has quite the Hollywood pedigree: Fran Drescher originally wore the same dress in the 1997 romantic comedy, “The Beautician and the Beast.”

Grande’s stylist, Law Roach, sourced the archival piece through Tab Vintage. The look was classic Mackie — the designer is known as the “Sultan of Sequins” for his sparkling, show-stopping creations worn by everyone from Cher and Whitney Houston to Tina Turner and, most recently, Taylor Swift.

“A woman who wears my clothes is not afraid to be noticed,” Mackie, 85, has famously said of his glamorous designs.

Grande and Roach have been conjuring fashion history throughout the current promotional circuit for “Wicked: For Good,” which comes out in theaters Nov. 21.

Recently, the “We Can’t Be Friends” singer paid homage to the original “Wizard of Oz” in a sleek 1940s gown by Gilbert Adrian, the MGM costume designer behind the classic 1939 film.

The singer recently debuted a major hair transformation, swapping her blond Glinda locks for glossy brunette waves. “it’s good to see me, isn’t it? 🫧” she captioned a mirror selfie on Instagram Wednesday, quoting one of her character’s signature lines.

The “Wicked: One Wonderful Night” special airs Thursday, Nov. 6, at 8 p.m. ET on NBC and streams the next day on Peacock.
