This dress has a fun history. It was designed by Adrian for Joan Crawford in The Bride Wore Red, though the movie itself is in black and white and the full beauty of the colour of the dress was not fully appreciated until later.
The dress makes its second appearance in The Big Store in a fashion show scene. Again the film is in black and white, though Groucho Marx, who escorts the model, does explain "This is a bright red dress" because "Technicolor is sooo expensive!"
Finally, the gown appeared in Du Barry Was A Lady, sans the cape, though this time finally in colour!
The gown, which supposedly weighed around 30 pounds, is still in existence and in extremely good condition considering its age.
