The Met Gala is not just about the fashion on the red carpet. For many celebrities, it’s just the beginning of a night of partying. And with the unwieldy nature of most gala looks, an outfit change is usually in order. This tradition of wearing multiple fashions is relatively new, but these days there is always a second designer look waiting in the wings. The best after-party looks adhere to a relaxed philosophy, with an emphasis on comfort and movement. Attendees can do a complete 180, switching from a glamorous gown to a more casual ensemble, or choose to step out with a daring skin reveal. For the gala’s most risk-taking stars, the only real rule is to go bold or go home.
