Kit; clothes (6)
I believe the answer is:
outfit
I believe this clue is a double definition.
'kit' is the first definition.
(synonyms)
'clothes' is the second definition.
(outfit is a kind of clothes)
(Other definitions for outfit that I've seen before include "gear" , "Costume" , "Complete set of clothes" , "Business" , "Equip for an enterprise" .)
