The dance number at the end was Eyrich's favourite moment to style from the whole film: "Besides the cast being there, there were also two other big groups, including a full dance troupe that worked throughout the movie to train dancers. They all had to have a specific colour palette and sparkly outfits as well. And then you have all the specialty background roles that we had to dress. There were hundreds of people all coordinated at once in this final look. It was a puzzle — a big, sparkly, shiny puzzle," she said.
As for the leads, Eyrich broke down each of their outfits. "We knew Barry (James Corden) had to be in a silver tux with a teal-y turquoise accent because it was scripted and matched the tux he wore when he was in high school. Then, almost everyone else had a custom design except for Trent (Andrew Rannells). His aqua, shiny blue suit was purchased. Dee Dee (Meryl Streep) was in a Dolce & Gabbana top that was actually a dress we cut into a tunic. Then we made her custom capri pants because to dance in. Angie (Nicole Kidman) wore a purchase, and Mr. Hawkins (Keegan Michael-Key) wore custom."
