In Rebecca, the movie is set in the French Riviera, yet none of the women wear stockings.

If you watch To Catch a Thief - filmed on location in the French Riviera 1954/5, every single woman wears hosiery.

Roman Holiday (made 1 year earlier) has a lengthy moment where the young Audrey Hepburn takes off her shoes and flexes her stocking feet.

In Marnie (1964) there's a scene where Tippi Hedren's stocking feet are almost fetishised by Hitchcock, as the camera watches her feet for a full 2 minutes as she creeps across the office seeking to avoid the cleaner.
