A man who is excessively concerned with his appearance and fashion, often vain and foolish, obsessed with clothing and looks.
From Middle English 'foppe' meaning fool or dunce, possibly from a Scandinavian root related to deception; evolved specifically to mean a fashionable but foolish man by the 1600s.
The Restoration era (1660s onward) absolutely loved mocking fops in plays and poems—men so obsessed with their curled wigs, silks, and perfumes that they became comedic characters, which says a lot about what 17th-century society considered ridiculous.
