A Fop, Fop became a pejorative term for a foolish man over-concerned with his appearance and clothes in 17th century England. Some of the very many similar alternative terms are: "coxcomb," fribble, "popinjay" (meaning "parrot"), fashion-monger, and "ninny." "Macaroni" was another term, of the 18th century, more specifically concerned with fashion.
See that fella over there, he is a proper fop with his tight jumper and shiny earring. I reckon he must be a Stonelake.
