For the past couple of springs, the Fifth Avenue storefront of Van Cleef & Arpels has been in full bloom thanks to the beautiful designs of Alexandre Benjamin Navet, a French artist. This year, much more of Fifth is sharing in the joyous sculptures. Van Cleef & Arpels has partnered with the Fifth Avenue Association to create immersive installations that reach from 49th Street to 57th. Expect butterflies, flowers, and a blend of pastel drawings and brightly colored architectural structures such as arches, benches, and pergolas. —Clara Molot
