Possibly airs clothing (4)
I believe the answer is:
sari
'clothing' is the definition.
(sari is a kind of clothing)
'possibly airs' is the wordplay.
'possibly' indicates an anagram.
'airs' with letters rearranged gives 'SARI'.
(Other definitions for sari that I've seen before include "Eastern garment" , "Traditional dress of Indian women" , "Hindu woman's dress" , "habit" , "Traditional dress of Hindu women" .)
