A “Bridgerton” producer said in a new behind-the-scenes book that the show’s costume designer created 1,800 dresses and spent $80,000 on costumes for the first season.

In a section of “Inside Bridgerton,” a new book about the making of the first two seasons of the hit Netflix series, authors Betsy Beers and Shonda Rhimes break down how season one costume designer, Ellen Mirojnick, created hundreds of costumes for the series.

The book shares a quote from Sarada McDermott, a producer on the first season, who said that they had a “factory” dedicated to costumes for the series.

“We had to stage an incredible amount of costumes,” McDermott said. “It cost a fortune to build a wardrobe: Ellen Mirojnick had a right merry time and would spend eighty thousand here and there on material. As the invoices came in, we’d say, ‘Oh, there goes Ellen, shopping again!'”

The producer added: “The factory ultimately held 1,800 dresses, all cataloged. Phoebe alone had 86 dresses.”

Also in the book, Mirojnick said the team made 7,500 pieces of costume including “all of the period-specific underwear.”

Costumes are a big part of “Bridgerton.” Besides being more colorful than the typical period drama, the show’s costumes are filled with hidden meanings.

Insider’s Claudia Willen previously reported that the Bridgerton family wear more subdued colors of blues and silvers to represent that they are traditional, whereas the Featheringtons wear bright citrus colors to represent that they are from new money.

During an interview with People in May, season two costume designer Sofia Canale said that she styled Penelope Featherington in a light-green dress in season two to symbolize the blending of the Featherington and Bridgerton family colors and foreshadow the character’s romance with Colin Bridgerton.
