Spring is upon us! For the third year in a row, it means the Fifth Avenue storefront of Van Cleef & Arpels will be in full bloom. French artist Alexandre Benjamin Navet’s illustrations adorn the windows, while the brand has partnered with the Fifth Avenue Association to create immersive installations on street corners from 49th all the way up to 59th (Central Park South). Think butterflies, flowers, pastel drawings, and brightly colored arches, benches, and pergolas. There’s a fountain, too. —Elena Clavarino
