If you were on Instagram at the weekend, you likely saw one, two, or perhaps a hundred photos of New York influencers at the Cou Cou Intimates pop-up, wearing perfectly cropped three-quarter sleeve tops and carrying bunches of flowers in woven baskets. All evidence of another Jane Birkin summer to come, replete with ’60s shift dresses, over-stuffed bags, and Repetto flats.

However, should you be keen to tap into a less predictable approach to Gallic style, Lily Collins just swerved Jane-approved ballet flats in favor of the kind of jazz shoes worn by Birkin’s erstwhile boyfriend, Serge Gainsbourg. Before Kaia Gerber and Olivia Rodrigo became inseparable from their Repetto ballet pumps, Gainsbourg was striding around in the brand’s lace-up Zizi style–now the shoe of choice for art school girls (and a certain Marc Jacobs).
