Dress like a folk-tale wolf we've heard about (4)
I believe the answer is:
wear
'dress' is the definition.
(both can mean a person's clothing)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for wear that I've seen before include "Have on - deteriorate from constant use" , "Exhaust" , "show" , "Become tiresome" , "Carry the burden" .)
