Dramatic attire (8)
I believe the answer is:
costumes
'dramatic attire' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for costumes that I've seen before include "Dramatic attire" , "Garbs worn in play and fancy dress ball" , "Clothes for stage or fancy dress balls" , "Dresses (up)" , "Outfits, fancy dress perhaps" .)
