Costume designer Daniel Orlandi dressed Emma’s Travers as a “stubborn woman who wouldn’t give up English tweeds”.
As Pamela Travers becomes more comfortable with Walt Disney and with California, she becomes slightly less buttoned-up and she wears a bright olive dress that accentuates Emma’s curves.

Orlandi says that he had to make the dress that P. L. Travers wears to the Mary Poppins premiere much more conservative than the one worn by the real Travers because he feared Emma Thompson looked too sexy compared to the austere lady she was bringing on stage.
