Honoring the princess’s timeless beauty and classic style, the collection contains more than 2,000 items centered around gowns, costumes and accessories worn or chosen by Princess Diana and other royals, including Kate Middleton, Duchess of Cambridge, and Wallis Simpson, Duchess of Windsor. A newly constructed 13,000-square-foot gallery houses the exhibit, which also contains an exclusive doll collection by doll and sculpture makers Crees and Coe, the Diana portrait watercolor quilt featured on a 1997 Newsweek cover, letters and invitations connected to the Royal Family and mementos from the House of Windsor. queenmary.com
