Both bare making garment (8)
I believe the answer is:
bathrobe
'garment' is the definition.
(bathrobe is a kind of garment)
'both bare making' is the wordplay.
'making' indicates an anagram.
'both'+'bare'='bothbare'
'bothbare' anagrammed gives 'BATHROBE'.
(Other definitions for bathrobe that I've seen before include "Towelling garment" , "you may take it after a shower" , "Towelling dressing-gown" , "Towelling dressing gown" , "freshly-washed clothing" .)
