[[Stella Bopbates]] was famous for designing hats around the year [[200100|200,100]]. [[Rose Tyler]] was asked this on the [[Satellite Five|Game Station]]'s version of ''[[The Weakest Link]]''. ([[TV]]: {{cs|Bad Wolf (TV story)}})

== Worn by the Doctor ==
{{main|The Doctor's hats}}
In many of their lifetimes, [[the Doctor]] wore [[The Doctor's hats|hats]], either as occasional style or as regular attire.
== The Doctor's hats ==
The [[First Doctor]] was wearing his favoured hat, an [[Astrakhan]], when he met his first human companions, [[Ian Chesterton|Ian]] and [[Barbara Wright|Barbara]]. ([[TV]]: {{cs|An Unearthly Child (TV story)}}) The [[Second Doctor]] had an early tendency to don and remark upon any hat he came across in the course of an adventure. ([[TV]]: {{cs|The Power of the Daleks (TV story)}}, {{cs|The Highlanders (TV story)}}, {{cs|The Underwater Menace (TV story)}})
In the majority of his lifetimes, [[the Doctor]] wore a hat on a regular or semi-regular basis. The incarnations that showed no particular interest in hats were the [[Sixth Doctor|Sixth]], [[War Doctor|War]], [[Ninth Doctor|Ninth]], [[Tenth Doctor|Tenth]] and [[Twelfth Doctor]]s.
=== First Doctor ===
[[File:HandsupDaleks.png|thumb|left|The [[Fourth Doctor]] covers a [[Dalek]]'s [[eyestalk]] with his hat ([[PROSE]]: {{cs|A Brief History of the Daleks (short story)}})]]
Later, the [[Fourth Doctor]] had a particular hat, a [[fedora]], which he wore quite regularly, ([[TV]]: {{cs|Robot (TV story)}} et al.) and the [[Fifth Doctor|Fifth]] ([[TV]]: {{cs|Castrovalva (TV story)}}) and [[Seventh Doctor]]s ([[TV]]: {{cs|Time and the Rani (TV story)}} et al.) both favoured [[panama hat]]s, each to their own style.
The [[First Doctor]]'s usual hat of choice was a {{w|karakul (hat)|karakul}} or [[Astrakhan]], a triangular hat often associated with [[Afghanistan]], or what one account called an "oddly shaped fur hat". ([[PROSE]]: ''[[Doctor Who and an Unearthly Child]]'') It was this hat he was wearing when he met [[Barbara Wright]] and [[Ian Chesterton]], as well as during his first adventure with [[Ben Jackson]] and [[Polly Wright]]. ([[TV]]: ''[[An Unearthly Child]]'', ''[[The War Machines]]'') However, he also possessed a kind of {{w|Panama hat}}, which he wore in hotter climes. He donned a white Panama when he was on the hunt for the [[Dalek]]s' [[taranium]] in [[Egypt]]. ([[TV]]: "[[Escape Switch]]")
This incarnation was not averse to occasionally playing dress-up. When in [[French Revolution|Revolutionary]] [[France]], he obtained period-appropriate wardrobe. Because the costume was that of a regional official, his hat was particularly elaborate, bearing a strong resemblance to an early [[18th century]] French army officer's hat. ([[TV]]: "[[A Change of Identity]]")
On noticing the Fifth Doctor actually kept a hat on his [[hatstand]] in [[the TARDIS]], the [[Tenth Doctor]] noted that he couldn't remember the last time he actually wore a hat. ([[AUDIO]]: {{cs|The Gates of Hell (audio story)}})
=== Second Doctor ===
[[File:11th Doctor wearing a Fez.jpg|thumb|right|The [[Eleventh Doctor]] in a [[fez]]. ([[TV]]: {{cs|The Big Bang (TV story)}})]]
[[File:SecondScottishLook.jpg|thumb|The [[Second Doctor]] in a {{w|Balmoral bonnet}} that he happened to find in [[Scotland]]. ([[TV]]: ''[[The Highlanders]]'')]]
The [[Eleventh Doctor]] would later find renewed enthusiasm in hats, which he would regularly pick up and don in an adventure, ([[TV]]: {{cs|The Big Bang (TV story)}}, {{cs|The Impossible Astronaut (TV story)}}, {{cs|Let's Kill Hitler (TV story)}}) like the Second Doctor. ([[TV]]: {{cs|The Power of the Daleks (TV story)}} et al.) The [[Thirteenth Doctor]] also expressed fondness for [[fez]]zes, ([[TV]]: {{cs|Kerblam! (TV story)}}) a particular favourite for the Eleventh Doctor. ([[TV]]: {{cs|The Big Bang (TV story)}}, {{cs|A Christmas Carol (TV story)}}, {{cs|The Day of the Doctor (TV story)}})
Early on, the [[Second Doctor]] was particularly obsessed with hats. One of his very first acts after [[regeneration]] was to rummage through a trunk in [[the TARDIS]] to find a [[stovepipe hat]] to wear. He wore the hat throughout his first adventure on [[Vulcan (The Power of the Daleks)|Vulcan]]. ([[TV]]: ''[[The Power of the Daleks]]'')
He sometimes uttered the phrase, "I would like a hat like that (or this)" if he saw a hat he particularly fancied. ([[TV]]: ''[[The Power of the Daleks]]'', ''[[The Highlanders]]'') In fact, when he arrived in [[Scotland]] in the [[18th century]], he happened across a {{w|Balmoral bonnet}} on a field of battle and immediately donned it. Later in the same adventure, he wore a [[British Army]] {{w|tricorn}} as a disguise.
== Worn by companions ==
Some of the Doctor's [[companion]]s also wore hats on a regular or occasional basis.
On a trip to [[Atlantis]], he briefly returned to the stovepipe, but continued to show his penchant for disguise by temporarily donning a gypsy headdress to appear as a merchant. It was here, too, that [[Polly Wright|Polly]] noted his fondness for hats. When he began enthusiastically eating food made of [[plankton]], the Doctor's praise was effusive. When [[Ben Jackson|Ben]] wondered why the Doctor was so excited, Polly replied, "I don't know. I've never seen him go for ''food'' like this before. It's usually hats." ([[TV]]: ''[[The Underwater Menace]]'')
[[File:Teazer.jpg|thumb|left|[[Ben Jackson]] in his Royal Navy cap. ([[TV]]: {{cs|The War Machines (TV story)}})]]
Those companions attached to [[UNIT]] or other armed forces wore hats as a part of their uniforms. [[Ben Jackson]]'s sailor's cap, for instance, identified him as a member of the crew of the [[HMS Teazer|HMS ''Teazer'']]. UNIT officers, like [[the Brigadier]] and [[Captain]] [[Mike Yates]], most often wore a rigid, green-and-red officer's cap, similar to the [[British Army]]. [[Surgeon-Lieutenant]] [[Harry Sullivan]]'s black, white and gold hat — otherwise quite similar to the standard Army issue — betrayed his secondment from the [[Royal Navy]]. [[Sergeant]] [[John Benton]] most often wore a beret in the field. Indeed, UNIT soldiers and officers alike wore [[beret]]s in the field. Over the years, the standard-issue UNIT field beret changed from chocolate brown ([[TV]]: {{cs|The Ambassadors of Death (TV story)}}) to khaki green ([[TV]]: {{cs|Terror of the Autons (TV story)}}) to [[United Nations]] blue ([[TV]]: {{cs|Battlefield (TV story)}}) to red. ([[TV]]: {{cs|Aliens of London (TV story)}}, {{cs|Planet of the Dead (TV story)}})
=== Third Doctor ===
{{video|The Doctor Meets Tegan - Doctor Who - Logopolis - BBC|thumb|[[Tegan Jovanka]] stumbles into [[the TARDIS]] in her [[stewardess]] uniform. ([[TV]]: {{cs|Logopolis (TV story)}})}}
Like his predecessor, the [[Third Doctor]] almost immediately donned a hat after his regeneration cycle ended. He found a {{w|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. ([[TV]]: ''[[Spearhead from Space]]'') However, he wore it only briefly and generally was without a hat for the rest of his life.
Although not in the military, a couple of companions nevertheless had headwear that was a part of a uniform. [[Tegan Jovanka]] had a triangular cloth cap as a part of her stewardess' uniform, but she largely abandoned its use after meeting the [[Fourth Doctor]] and [[Adric]]. ([[TV]]: {{cs|Logopolis (TV story)}}) Likewise, while [[Nyssa|Nyssa of Traken]] was "in uniform" as a [[Trakenite]] royal, she wore a tiara. ([[TV]]: {{cs|The Keeper of Traken (TV story)}})
=== Fourth Doctor ===
These exceptions aside, most companions simply didn't wear hats on anything like a regular basis. A few wore the ''occasional'' hat strictly as a fashion accessory, often whimsical.
[[File:Sombrero.jpg|thumb|left|The Fourth Doctor's [[sombrero]]. ([[COMIC]]: ''[[Doctor Who and the Star Beast (comic story)|Doctor Who and the Star Beast]]'')]]
Just like his previous selves, the [[Fourth Doctor]]'s initial clothing instincts were to reach for a hat after his regeneration. His outfit was supplied entirely from the [[TARDIS wardrobe]] and he tried on a variety of outfits, most of them with hats. Amongst the rejected hats were a [[Viking]] helmet and a tall [[clown]]'s hat. Finally he settled on a wide-brimmed [[fedora]]. Unlike the two incarnations before him, however, he fairly consistently used this hat or ones very like it throughout his life.
On occasion, he substituted another hat, such as when he again donned a {{w|Balmoral bonnet}} whilst in [[Scotland]]. ([[TV]]: ''[[Terror of the Zygons]]'') He also wore a [[sombrero]] when he thought he was arriving in [[Benidorm]], [[Spain]]. ([[COMIC]]: ''[[Doctor Who and the Star Beast (comic story)|Doctor Who and the Star Beast]]'') He also wore a {{w|deerstalker}} while visiting Victorian London to go along with his [[Sherlock Holmes]]-styled outfit. ([[TV]]: ''[[The Talons of Weng-Chiang (TV story)|The Talons of Weng-Chiang]]'') and briefly a bowler hat when investigating [[Fang Rock lighthouse]]. ([[TV]]: ''[[Horror of Fang Rock (TV story)|Horror of Fang Rock]]'')
=== Fifth Doctor ===
Like the incarnation before him, the [[Fifth Doctor]] had a regular hat, which he wore throughout his life. From his first adventure, he carried with him a roll-up {{w|Panama hat}} with a hat band of the same colours as the rest of his outfit. He tended to wear it upon first exiting [[the TARDIS]] in a new location, but often quickly rolled it up and put it back in his jacket.
=== Seventh Doctor ===
In both her incarnations, [[Romana]] was fond of wearing hats. [[Romana I]] wore a [[flat cap]] on her first visit to [[Earth]] ([[TV]]: {{cs|The Stones of Blood (TV story)}}) and an elaborate purple-and-green hat that was "what everyone... [was] wearing" on [[Tara (planet)|Tara]]. ([[TV]]: {{cs|The Androids of Tara (TV story)}}) [[Romana II]] briefly toyed with wearing the Fourth Doctor's fedora after her [[regeneration]]. She later wore a [[boater]] when [[punt]]ing in [[Cambridge]] ([[TV]]: {{cs|The Five Doctors (TV story)}}) and a straw sun hat whilst on a beach. ([[TV]]: {{cs|The Leisure Hive (TV story)}})
Like the Fifth Doctor, the [[Seventh Doctor]] also had a {{w|Panama hat}}, though it was of a different design. He wore it constantly, even when indoors. He typically removed it from his head to greet others or in respect of someone recently deceased. ([[TV]]: ''[[Time and the Rani (TV story)|Time and the Rani]] - [[Survival (TV story)|Survival]]'') When he took to wearing a darker jacket, he also changed his hat into a subtly darker one. ([[TV]]: ''[[Battlefield (TV story)|Battlefield]]'') Whilst in the vault underneath [[Windsor Castle]] in [[1988]], he briefly wore a [[fez]]. ([[TV]]: ''[[Silver Nemesis (TV story)|Silver Nemesis]]'')
=== Eighth Doctor ===
[[File:SJS hat.jpg|thumb|left|[[Sarah Jane Smith|Sarah Jane]] wearing a hat while visiting the [[National Institute for Advanced Scientific Research]]. ([[TV]]: {{cs|Robot (TV story)}})]]
[[Liz Shaw]] generally didn't go in for hats, but did once wear a white, broad-brimmed hat to drive [[Bessie]]. ([[TV]]: {{cs|The Ambassadors of Death (TV story)}}) Likewise, [[Sarah Jane Smith]] was mostly hat-less but did wear a casual spring hat whilst investigating the [[National Institute for Advanced Scientific Research]]. ([[TV]]: {{cs|Robot (TV story)}})
After his [[regeneration]] in [[San Francisco]] on [[31 December]] [[1999]], the amnesiac [[Eighth Doctor]] ransacked the lockers of the hospital staff for a new outfit. He decided against the stetson that went with the "[[Wild Bill Hickok]]" costume which he chose to steal. ([[TV]]: ''[[Doctor Who (TV story)|Doctor Who]]'')
The Doctor once emerged from the TARDIS wearing a [[fez]] when he believed that he had materialised in [[Egypt]]. ([[COMIC]]: ''[[Doctor Who and the Nightmare Game (comic story)|Doctor Who and the Nightmare Game]]'')
== Others ==
[[Tom Cardwell]] wore a [[tin foil hat]], which according to [[Lucie Miller]], was "not a good sign at all". ([[AUDIO]]: {{cs|Blood of the Daleks (audio story)}})
On another occasion, when visiting the [[Lakota Sioux]] Nation in [[1875]], he wore a [[stetson]] which was given to him by [[Samuel Clemens]]. ([[COMIC]]: ''[[Bad Blood (comic story)|Bad Blood]]'')
[[Graham O'Brien]] described the [[Cyber-helmet]] as a hat. ([[TV]]: {{cs|The Timeless Children (TV story)}})
=== Tenth Doctor ===
[[Lucifer (Lucifer)|Lucifer]] wore a [[brown]] [[parka]] and [[black]] hat. ([[WC]]: {{cs|Mission: Find Lilith (webcast)}})
The [[Tenth Doctor]] showed little interest in hats, although he did once, briefly, sport a fez that fell out of a time fissure before it was snatched off of his head by his [[Eleventh Doctor|future self]]. ([[TV]]: ''[[The Day of the Doctor]]'')
He, at one point, wore straw hat, along with sunglasses and a [[lei]], implying he had just finished a relaxing time at a beach. ([[TV]]; ''[[The End of Time (TV story)|The End of Time]]'') He also donned a [[sombrero]] on the beaches of [[Centuria]]. ([[COMIC]]: ''[[The Power of the Cybermen (comic story)|The Power of the Cybermen]]'')
== Other references ==
Claiming that she could save the universe from the [[final Flux event]], the [[Thirteenth Doctor]] told [[the Division]]'s [[Ood (Survivors of the Flux)|Ood]] that she was "very good at pulling [[rabbit]]s out of hats." When the [[Ood]] stated that he had neither rabbits nor hats, the Doctor explained that it was a [[metaphor]]. ([[TV]]: {{cs|Survivors of the Flux (TV story)}})
=== Eleventh Doctor ===
The [[Eleventh Doctor]] wore a variety of hats, seeking to acquire unique ones. This Doctor, even more so than the Second Doctor, possessed a rather obsessive desire to wear a hat; he'd get distracted by a hat he liked even while running away from enemies. ([[TV]]: ''[[The Big Bang]], [[The Curse of the Black Spot]]'') He considered damaging a hat to be offensive. ([[TV]]: ''[[A Town Called Mercy]]'') Unfortunately for him, [[River Song|his wife]] had a habit of shooting his hats right off his head. ([[TV]]: ''[[The Big Bang]], [[The Impossible Astronaut]]'')
[[File:11th_Doctor_wearing_a_Fez.jpg|thumb|left|The [[Eleventh Doctor]] tries out his fez. ([[TV]]: ''[[The Big Bang]]'')]]
While in the [[National Museum]], he found a [[fez]] of which he became instantly fond. The fez was later removed by [[Amy Pond]] and destroyed by [[River Song]]. Undeterred, he noted to himself that it would be easy to buy another one. ([[TV]]: ''[[The Big Bang]]'') He wore one while acting as an extra in a film Rory and Amy were watching ([[TV]]: ''[[The Impossible Astronaut]]''), and even acquired one previously owned by his old pal [[Albert Einstein]]. ([[TV]]: ''[[Death is the Only Answer]]'') He later wore one on a Christmas trip with [[Kazran Sardick]] and [[Abigail Pettigrew]] to [[Egypt]] ([[TV]]: ''[[A Christmas Carol (TV story)|A Christmas Carol]]'') and had one in [[2013]] [[London]]. ([[TV]]: ''[[The Bells of Saint John (TV story)|The Bells of Saint John]]'') When he and [[Clara Oswald]] investigated the [[National Gallery]], due to the summons of [[Queen Elizabeth I]], he spotted a fez inside a display case and immediately put it on. When Clara noticed, she commented that one day, he was going to be able to just walk past a fez while the Doctor declared that was never going to happen. It was later used to test the safety of a time fissure. ([[TV]]: ''[[The Day of the Doctor]]'')
[[File:Stetson.jpg|thumb|The [[Eleventh Doctor]] relaxes in [[Utah]] with his [[Stetson]]. ([[TV]]: ''[[The Impossible Astronaut]]'')]]
The Doctor later showed a fondness for [[stetson]]s, being given one by [[Craig Owens]] as a gift for his trip to [[Utah]]. ([[TV]]: ''[[Closing Time (TV story)|Closing Time]]'') He wore his gift during his investigation to find out [[The First Question|why the Silence wanted him dead]], and made the ''[[Teselecta]]'' copy the stetson along with his form. The copied Stetson was shot off by River. ([[TV]]: ''[[The Impossible Astronaut]]/[[The Wedding of River Song]]'') Having not brought his own with him, the Doctor borrowed a stetson that had been damaged by a shot fired by [[Kahler-Tek|the Gunslinger]]. ([[TV]]: ''[[A Town Called Mercy]]'')
This version of the Doctor also owned a top hat, which he wore at Amy and [[Rory Williams|Rory]]'s wedding, ([[TV]]: ''[[The Big Bang]]'') after having been poisoned by River in [[Nazi]] [[Germany]] ([[TV]]: ''[[Let's Kill Hitler]]'') and again to conceal a device that allowed him to lure the [[Squall]] back into their dimension of origin ([[PROSE]]: ''[[Paradox Lost]]''). He also wore one as part of his Victorian Era clothing while brooding over the loss of Amy and Rory. ([[TV]]: ''[[The Snowmen]]'')
While posing as [[Sherlock Holmes]], he also wore a deerstalker hat similar to the one his [[Fourth Doctor|fourth incarnation]] had during a previous visit to Victorian London. ([[TV]]: ''[[The Snowmen (TV story)|The Snowmen]]'') Later, the Doctor wore a bowler hat. ([[TV]]: ''[[The Crimson Horror]]'')
