Attire, apparel (7)
I believe the answer is:
raiment
This clue is a double definition.
'attire' is the first definition.
(I've seen this in another clue)
'apparel' is the second definition.
(I know that apparel can be written as raiment)
(Other definitions for raiment that I've seen before include "Garb" , "Gear" , "Am inert (anag) - clothing" , "Especially fine or decorative clothing" , "Something put on" .)
