The costumes exhibited were made by COSPROP.
The exhibit was divided into 3 areas: "Section one [showed] costumes about historical figures such as Elizabeth I, Louis XIV, Thomas Jefferson, and [covered] the era from the 16th to 19th centuries. Also included in this section [were] costumes from Ever After, Dangerous Liaisons, and movies based on Jane Austen's books."
"Section two [displayed] costumes from classic literary movies set from 1827 to the late 19th century - such as Eugene Onegin, Portrait of a Lady, The Golden Bowl and more."
"Section three [progressed] into the 20th century with costumes from such films as Titanic, Evita, Room With a View, Gosford Park and others." - from Judy Mitchell's article http://www.alleycatscratch.com/exhibit/Fashion-In-Film.htm
One of the exhibition venues was the Winterthur Museum & Country Estate in Delaware.
