"Quentin Crisp once remarked something like,'Style is knowing what you are and being able to purvey. Fashion is simply not being able to decide what you are.' "   

Yes! - or do I mean "wicked!"?

Someone else (or maybe it was Crisp again?) also described fashion as "an alternative to style for people with no taste". But my preferred definition is an economic one - "fashion is a device to make us buy new clothes before the old ones are worn out."

Wassail!
