Fall loosely (5)
I believe the answer is:
drape
'fall loosely' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for drape that I've seen before include "Wrap loosely (with cloth)" , "Hang - curtain" , "Cover with a loose cloth" , "Cover loosely with cloth" , "Swathe" .)
