Astrakhan
From Tardis Wiki, the free Doctor Who reference
An Astrakhan was a wool hat with the two points on the top. The First Doctor wore one (DW: [[An Unearthly Child]).
Behind the Scenes
The Eleventh Doctor considered wearing one, even having the thought of going back in time to steal it from himself, which River disapproved of. (The Brilliant Book 2012)
