Strangely right, a new pair of pyjamas, perhaps? (9)
I believe the answer is:
nightwear
'pair of pyjamas perhaps?' is the definition.
'strangely right a new' is the wordplay.
'strangely' is an anagram indicator.
'right'+'a'+'new'='rightanew'
'rightanew' is an anagram of 'NIGHTWEAR'.
(Other definitions for nightwear that I've seen before include "evening dress" , "What's on after the watershed" , "this brings bed to mind?" , "Bed clothing (W, not G)" , "negligee, say" .)
