hi,

The Met Gala formally called the Costume Institute Gala or the Costume Institute Benefit and also known as the Met Ball, is an annual fundraising gala for the benefit of the Metropolitan Museum of Art's Costume Institute in New York City. It marks the opening of the Costume Institute's annual fashion exhibit. Each year's event celebrates the theme of that year's Costume Institute exhibition, and the exhibition sets the tone for the formal dress of the night since guests are expected to choose their fashion to match the theme of the exhibit.

Affectionately referred to as “fashion’s biggest night out,” the Met Gala  is a fundraising benefit for the Metropolitan Museum of Art in New York City. The event welcomes stars, young creatives, and industry paragons.
