n a men’s felt-type hat (generally brown). The hat inherited its name from the 1894 George du Maurier novel, Trilby. The novel was not about hats, and if it even mentioned a hat it was only really in passing. However, during the first stage adaptation of the novel, one of the main characters wore a hat of an as-yet-unnamed type. Someone evidently thought that this was a good a time as any to name the hat, and so it was.
