The Dressmaker (US title The Secret Glass) is a gothic psychological novel written by Beryl Bainbridge. In 1973, it was shortlisted for the Booker Prize. Like many of Bainbridge's earlier works, the novel is semi-autobiographical. In particular, the story was inspired by a relationship that she had with a soldier as a teenager. The characters of Nellie and Margo were based upon two of her paternal aunts.
