Ruth E. Carter Talks the Meanings Behind "Black Panther: Wakanda Forever" Costumes

"The biggest challenge costume design [we] faced was for the underwater performance. We had a first test scene where M'Baku, head of the Jabri, is supposed to make a deep dive underwater. When we first tested M'Baku, he floated like a log. It was after that we learned that we would be making multiple builds of the various costumes that adapted to the buoyancy of the underwater world as well as performed eloquently on land."
