Courrèges made the bag before the miniskirt.
The AC logo appeared on Courrèges bags in 1965 — before the miniskirt collection that made the house famous. The proportions haven't changed.

In 1991 Courrèges showed in Paris. Two models walked in olive coats. The AC-logo bag shapes from 1965 were still in production. Twenty-six years. Same hardware.

Nicolas Di Felice relaunched Courrèges in 2021. The Holy and Egg bags are the AC-logo shapes, reissued. The original is sixty years old.

How to date an AC-logo bag: PVC logo = pre-1975. Embossed leather = 1975–1990s. Silver-tone hardware screws = 1990s onward. 'Courrèges Paris' stamp inside = authentic.
