Company uniform (6)
I believe the answer is:
outfit
I believe this clue is a double definition.
'company' is the first definition.
(I've seen this before)
'uniform' is the second definition.
(I know that outfit is a type of uniform)
(Other definitions for outfit that I've seen before include "Costume" , "complete set of equipment" , "what to wear?" , "Organistion or set of clothing" , "gear" .)
