Girl hiding stolen garment (5)
I believe the answer is:
dhoti
'garment' is the definition.
(dhoti is a kind of garment)
'girl hiding stolen' is the wordplay.
'girl' becomes 'di'.
'hiding' means one lot of letters goes inside another.
'stolen' becomes 'hot' (I've seen this before).
'di' enclosing 'hot' is 'DHOTI'.
(Other definitions for dhoti that I've seen before include "garment in India" , "Indian loincloth" , "Simple Indian garment" , "pants in Goa?" , "Hindu loincloth" .)
