Midway through January, Chloë Sevigny Instagrammed a photo of herself with an unbuttoned cardigan that, to most, was simply an official confirmation of her first pregnancy. But the photo that Sevigny geotagged “Baby on Board” originally had a different significance; it was Jim Jarmusch’s contribution to “…Photographers…Artists…and the Snap Cardigan,” an exhibition that marks the 40th anniversary of agnès b.’s signature design. Jarmusch is just one of more than 70 creatives who worked on the project, as are David Lynch and Juergen Teller. But the fact that that’s a downgrade is a true testament to the designer’s (under-recognized) legacy; Agnès started her own art gallery, Galerie du Jour, in 1983, and first showcased 140 photographers’ interpretations of her snap cardigan there in in 1986. She was one of the first to discover heavyweights like Keith Haring and Jean-Michel Basquiat, and these days, she’s still one of the first to champion up-and-comers like the self-portraitist Omar Victor Diop.
