Kilt
From Tardis Wiki, the free Doctor Who reference
A kilt was a knee-length skirt-type garment originating in the traditional dress of men and boys in the Scottish Highlands. [source needed]
Jamie McCrimmon spent his time travelling with the Second Doctor wearing his kilt, even when it was too cold to do so. (TV: The Highlanders, TV: The Abominable Snowmen et all)
When the Fifth Doctor was giving Erimem a tour of the TARDIS, he told her the kilt in the wardrobe belonged to Jamie. (AUDIO: No Place Like Home)
Burrows compared Captain Kybo's uniform to a kilt. (AUDIO: Judoon in Chains)
