Befits (5)
I believe the answer is:
suits
'befits' is the definition.
('suit' can be a synonym of 'befit')
This is all the clue.
(Other definitions for suits that I've seen before include "Sets of clothes designed to be worn together" , "Hearts, clubs, diamonds, spades" , "Formal garments" , "Becomes; formal wear" , "is flattering" .)
