Ariana Grande went back down the yellow brick road to give fans a glimpse of the early days of Wicked as the musical-turned-movie dominates the box office.

Paul Tazewell used his own magic to create the incredible costumes in “Wicked.” But making one iconic outfit — worn by Ariana Grande’s Glinda the Good Witch — was not an easy feat for the 60-year-old costume designer.

“I love fantasy work as a designer,” says Tazewell, who designed the costumes for Lin-Manuel Miranda’s Broadway musicals “Hamilton” and “In the Heights,” the latter of which was adapted for the screen by “Wicked” director Jon M. Chu. “I also love period work. And this ends up being a combination of both.”
