There are rules, even in fancy dress. Do not block the doors while adjusting your angel wings. Be aware of your tail—you don’t want to smack a reading passenger in the face.
Most importantly, embrace the interaction. If someone asks for a photo, take a dramatic pose. You’re a living, breathing piece of London’s unofficial performance art for thirty seconds.
And if your hat falls on the tracks? Let it go. It’s now part of Tube history.
A Note on Spontaneity
Not all fancy dress is planned. Sometimes a commuter just buys a fake moustache from a shop at the station. That accidental moustache can spark a smile that changes someone’s entire morning.
The beauty of this tradition is its democratic chaos. Bankers, students, tourists, and pensioners all become equal under the fluorescent lights, united by a shared joke.
