Joan Didion modeling sunglasses for Céline felt important, but Karen Walker's Spring ad campaign is monumental—especially if you're a dog person. The campaign stars Instagram celebrity Toast the King Charles Spaniel (son of The Fat Jewish), his fuzzy, adorable little face adorned with stylish oversized specs. Toast has been popular on Instagram for a minute now, with 157k followers obsessed with eternally lolling tongue. This isn't Toast's first dalliance with fashion (here's him decked out in Moschino), but this marks his first high-end official campaign. See two more snaps below, then head over to Style.com for the full lookbook.
