The seductively deep purple shirt that adorns the ever so beautiful torso of Sherlock Holmes ; renowned for sending all who gaze upon it into the throes of blind lust regardless of gender or sexual orientation; a potent aphrodisiac.

It's first appearance is in "The Great Game", the third episode of BBC's "Sherlock" starring Benedict Cumberbatch and Martin Freeman.
