11. There is a Costume Shop in the Metropolitan Opera House

Perhaps the most bustling area of the back of house is the costume shop, which has the feel of a European fashion house atelier. Large windows on the fourth floor flood light into the two-section space where 50 to 110 designers are at work, the numbers dependent on the production. Over the course of a season, the costume shop makes approximately 1,600 pieces of clothing and 50,000 millinery pieces, which include hats, crowns and headgear.
