Vogue offers a modern guide to women’s black-tie attire. While floor-length gowns are generally recommended, shorter dresses can work if exceptionally stylish or the host is known to be less formal. The invitation itself provides clues, with more formal invites suggesting longer gowns. Accessorizing is key, with statement jewelry adding a contemporary twist. It’s chic to repeat outfits and build a versatile capsule wardrobe.
