Fuss over one's appearance (5)
I believe the answer is:
preen
'fuss over one's appearance' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for preen that I've seen before include "demonstrate pride" , "Array (oneself) carefully" , "Perfect one's appearance" , "Tidy/clean (feathers)" , "Vainly groom oneself" .)
