Princess imported stolen Indian garment (5)
I believe the answer is:
dhoti
'indian garment' is the definition.
(I've seen this before)
'princess imported stolen' is the wordplay.
'princess' becomes 'di' (Princess Diana).
'imported' indicates putting letters inside.
'stolen' becomes 'hot' (stolen goods are 'hot').
'di' placed around 'hot' is 'DHOTI'.
(Other definitions for dhoti that I've seen before include "Indian loincloth" , "Hindu loincloth" , "Loin cloth" , "Indian attire" , "article of clothing" .)
