Maybe airs a dress (4)
I believe the answer is:
sari
'a dress' is the definition.
(I know that sari is a type of frock)
'maybe airs' is the wordplay.
'maybe' indicates anagramming the letters.
'airs' anagrammed gives 'SARI'.
(Other definitions for sari that I've seen before include "Asian dress" , "Hindu woman's dress" , "Eastern garment" , "Hindu female garment" , "Traditional Indian garment" .)
