More air circulating in wardrobe (7)
I believe the answer is:
armoire
'wardrobe' is the definition.
(armoire is a kind of wardrobe)
'more air circulating' is the wordplay.
'circulating' indicates anagramming the letters.
'more'+'air'='moreair'
'moreair' is an anagram of 'ARMOIRE'.
'in' acts as a link.
(Other definitions for armoire that I've seen before include "Cabinet originally used for storing weapons" , "Large wardrobe - more air (anag)" , "Large wardrobe or cabinet" , "item of furniture" , "Cupboard" .)
