Draped garment (4)
I believe the answer is:
toga
'draped garment' is the definition.
(I know that toga is a type of draped garment)
This is the entire clue.
(Other definitions for toga that I've seen before include "Cloak of ancient Rome" , "Ancient Roman garment" , "garment of old" , "Sheet draped round Roman" , "Garment worn by men in ancient Rome" .)
