Coat to take to the cleaners (6)
I believe the answer is:
fleece
I believe this clue is a double definition.
'coat' is the first definition.
(I know that fleece is a type of coat)
'take to the cleaners' is the second definition.
(both can mean to cheat or defraud)
'to' acts as a link.
(Other definitions for fleece that I've seen before include "Swindle - wool removed from sheep" , "Rip off" , "Warm jacket" , "thermal garment" , "Warm coat; swindle" .)
