Like a dandy (7)
I believe the answer is:
foppish
'like a dandy' is the definition.
(dandy and fop can mean a fashionable man)
This is the entire clue.
(Other definitions for foppish that I've seen before include "of the Dandy" , "Wet" , "Dandyish" , "Excessively concerned with fashion and elegance" , "like Beau Brummell" .)
