La Piscine (1969)

The grandaddy of stylish pool inspiration: Jacques Deray’s 1969 thriller starring Alain Delon, Romy Schneider and a very young Jane Birkin. With costumes by Courrèges and a stunning Côte d’Azur pool serving as the backdrop for both steamy sex and something much darker. La Piscine is the stuff of mood-board dreams. It’s also a perennial designer reference, popping up in collections from Tory Burch and Simon Porte Jacquemus.
