Possibly airs attire (4)
I believe the answer is:
sari
'attire' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'possibly airs' is the wordplay.
'possibly' indicates anagramming the letters.
'airs' anagrammed gives 'SARI'.
Can you help me to learn more?
(Other definitions for sari that I've seen before include "Asian dress" , "Something worn" , "habit" , "Traditional dress of Indian women" , "Traditional Indian women's dress" .)
