Trilby
From Tardis Wiki, the free Doctor Who reference
A trilby was a type of hat.
The Third Doctor found a trilby amongst a physician's clothes at the Ashbridge Cottage Hospital. When he tried it on and looked in a mirror, he seemed to give it a look of approval. However, he wore it for only a short time. (TV: Spearhead from Space [+]Loading...["Spearhead from Space (TV story)"])
