Ariana Grande followed the yellow brick carpet, instead of the red carpet, on the way to the Nov. 3 premiere of Wicked in Sydney, Australia. Celebrating her role of Glinda, the pop star and actress aptly dressed in a pink gown that looks straight out of Oz — though it’s actually custom Vivienne Westwood.

With a voluminous tulle skirt, a corset-style bodice, a sheer, puffed sleeve at the shoulder and sparkling, starburst embellishments, Grande’s dress is in homage to the costume actress Billie Burke famously wore as Glinda in the 1939 film The Wizard of Oz.

Grande topped off Vivienne Westwood’s spot-on take of Glinda’s look with a diamond butterfly choker by Lorraine Schwartz, stylist Mimi Cuttrell shared on Instagram. The necklace was another nod to the Glinda movie ensemble from the 1939 classic.

Cynthia Erivo, Grande’s Wicked co-star who portrays Elphaba, wore a sculptural dress by Louis Vuitton, with a sleek, strapless, corseted bodice and a statement skirt for the Nov. 3 premiere the State Theatre. The black gown was a modern nod to the Wicked Witch of the West, without the traditional witch hat. Like Grande, Erivo also accessorized with a choker — hers bearing an eye-catching lion, a piece by Roberto Coin, according to the fashion credits stylist Jason Bolden tagged on Instagram.

Wicked, the first of the story’s two-part, big screen adaptation, opens in movie theaters on Nov. 22.
