At first glance, Nicole Kidman’s outfit appears somewhat, dare we say, basic. But, ça alors! The look is in fact the maddeningly effortless work of Celine designer Hedi Slimane, who brings an unparalleled sense of precision to the humble blue jeans, to the slouchy grey sweater, and to the black boot. He is so obsessed with these simple pieces—the uniform of the young and rebellious—that they appear in every one of his collections. And, as Kidman demonstrates, Slimane’s rock ’n’ roller Saint Laurent years have ceded to a slightly softer (but no less glamorous) expression of bourgeois ’70s Paris at Celine. And that’s why we’re ready to officially declare the end of Hot Girl Summer. Nicole Kidman’s Big Fit of the Days marks the beginning of French Girl Fall.
