“So ‘Romeo and Juliet’ is on stage right now, the first time they are all in costume, so we will be dealing with that later today, going down to take any notes from stage with any running problems,” said Elizabeth King, the head of the revival workroom. “We are also fitting ‘Andrea Chénier’ and ‘Billy Budd’ and still fitting a little bit of ‘Faust.’ So there are usually four productions in different stages that we are working on at the same time.”

The revival department devotes its time to ballet and opera productions that have been performed before, like the Nicholas Georgiadis-designed “Romeo and Juliet,” for which some of the original costumes from 1965 are still being used. The entire costume department, which works on more than 5,000 pieces each season, has 110 full-time staff members and up to 80 freelancers, spread out across almost all floors of the opera house in Covent Garden, from the stock room, pattern room, and the men’s and ladies’ workroom (which focus on new production designs) to the dye room, wig room, shoe room, hats, jewelry and makeup.
