Steal coat (6)
I believe the answer is:
fleece
I believe this is a double definition.
'steal' is the first definition.
(thesaurus)
'coat' is the second definition.
(fleece is a kind of coat)
(Other definitions for fleece that I've seen before include "Animal coat - charge exorbitantly" , "Plunder; charge (someone) exorbitantly" , "Woollen coat of sheep" , "Diddle" , "Woolly hair of sheep" .)
