Looker unwilling to don jacket of curious rags (10)

'rags' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps there's a link between them I don't understand?

'looker unwilling to don jacket of curious' is the wordplay.
'looker' becomes 'dish' (I've seen this in another clue).
'unwilling' becomes 'loth' (similar in meaning).
'to don' means one lot of letters goes inside another (don can mean to wear).
'jacket of' says to hollow out the word (remove centre letters) (only the word's outer letters or 'jacket' remain).
'curious' with its centre taken out is 'cs'.
'loth' put into 'cs' is 'cloths'.
'dish'+'cloths'='DISHCLOTHS'
