Stella McCartney dug into her archives this season, reimagining early-'00s hits (including some from her Chloé days) with today's sustainable innovations—and a new collaboration with artist Yoshitomo Nara's depictions of children. Constructed into a tailored, oversized silhouette, this retro, double-breasted blazer features peaked lapels, duo welt pockets, and tonal button details through the front. Try it layered over a silk skirt and kitten heels for stylishly timeless look.
