Stylish dresser (3)
I believe the answer is:
fop
'stylish dresser' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for fop that I've seen before include "A dandy, overdressed man" , "exquisite" , "Man excessively concerned with his appearance" , "Gallant" , "'Dandy, coxcomb (3)'" .)
