MET Gala 2012
The Costume Institute Gala (or Costume Institute Ball), known as the Met Ball, is an annual ball that celebrates the annual opening of the Metropolitan Museum’s (The Met) fashion exhibit at the Costume Institute.
Fashion industry experts and style magazines consider the event, which is hosted by Vogue, to be the fashion world’s best red carpet event.
It is regarded as the top annual social event in New York City. The event has been an annual affair at the Met since 1948 (the year in which the Costume Institute was founded), but it has been held in different parts of the museum over the years.
