What is the name of Tim Burton's frequent costume designer?

The name of Tim Burton’s frequent costume designer is Colleen Atwood.

Atwood is an American costume designer known for creating distinctive wardrobes that reinforce a film’s characters, setting, and visual mood. Her collaboration with Burton began with Edward Scissorhands and continued across films including Ed Wood, Sleepy Hollow, Planet of the Apes, Big Fish, and Sweeney Todd: The Demon Barber of Fleet Street.

She has also designed costumes for directors such as Jonathan Demme and Rob Marshall. Atwood won Academy Awards for Chicago, Memoirs of a Geisha, Alice in Wonderland, and Fantastic Beasts and Where to Find Them. Her work on Alice in Wonderland made her a particularly natural partner for Burton’s heightened, storybook aesthetic.

A common mix-up is confusing a costume designer with a film’s actors or production designers. Mary Zophres, Sandy Powell, and Edith Head are all prominent costume-design names, but none is Burton’s signature recurring costume collaborator. Atwood later designed costumes for Burton’s Wednesday as well.
