Belle de Jour is a French film from 1967 starring Catherine Deneuve, Jean Sorel and Michel Piccoli. It is based on the 1928 novel by Joseph Kessel and is about a young woman who is compelled to spend her midweek afternoons as a prostitute while her husband is at work. The clothes worn by Catherine Deneuve's character are so stylish, here are a few of my favourites:
This is such a lovely military coat, you can't see it in the picture but Catherine is wearing a Roger Vivier Pilgrim pump in black patent. You can read more about the shoe here.
