Garment to take to the cleaners (6)
I believe the answer is:
fleece
This clue is a double definition.
'garment' is the first definition.
(I've seen this before)
'take to the cleaners' is the second definition.
(both can mean to cheat or defraud)
'to' is the link.
(Other definitions for fleece that I've seen before include "Con" , "Sheepskin lining" , "Sheepskin - strip - swindle" , "Rook; animal's coat" , "Swindle; sheep's coat" .)
