Solitude-seeker shedding old clothes (4)
I believe the answer is:
garb
'clothes' is the definition.
(garb is a kind of clothes)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for garb that I've seen before include "Distinctive dress of a group" , "Covering" , "Kit" , "costume" , "Dress - clothing" .)
