The final "courtesan" dress in Gigi is just spectacular. It's way too simplistic for the era, but it fits the character, which is more important, in the end. Plus, I adore the half moon hair pin (which you unfortunately can't see in this publicity photo).
Directed by Vincente Minnelli. With Leslie Caron, Maurice Chevalier, Louis Jourdan, Hermione Gingold. Weary of the conventions of Parisian society, a rich playboy and a youthful courtesan-in-training enjoy a platonic friendship, but it may not stay platonic for long.
