Nobody knows. No seriously, nobody. It’s been going on since the late 1990s, and it’s become such a big deal that there are even prizes for the best fancy dress costumes on show at big darts venues like the Alexandra Palace or ‘ally pally’ as it’s known.


In December 2016, one darts fan showed his love for the game by dressing up as a giant dart board and other popular costumes this year include vicars, the Teletubbies and brash suits - especially stripes and Union Jacks.


Group costumes are super popular and our favourite theme for 2017 is fancy dress zoo costumes where one person dresses up as the lion tamer and everybody else chooses an animal costume - suitable for all ages and sizes, we think this is a real winner! And it’s also the best way to get yourself on TV if you’re attending the darts and want to be featured in the crowd shots.
