Costume poster
Miss Pettigrew Lives for a Day is not the kind of movie that I would have seen either when it came out in 2008 (I’m really not much of a movie person) and I found the costume from the Cut! exhibit to be pretty underwhelming, though I had a friend who quite liked it.
The poster (click for a larger version) says:
“Amy Adams as Delysia LaFosse
Amy Adams wears a day dress of a colour called “Wallis Blue” named after the Duchess of Windsor. The short dress has a self bow at the neck and a sash with a tortoise shell buckle at the waist. The matching hat gives the whole (ensemble) some added oomph”
The movie is set in London in 1939.
Honestly, the only part of the outfit that I cared for was the hat!
Delysia LaFosse's hat
It’s an almost-matching (but not quite) blue with a red hatband, red binding/trim, and a red pin.
This outfit is shown in the movie trailer in a number of scenes.
