Wrinkly? Daring to go topless (3)
I believe the answer is:
old
'wrinkly?' is the definition.
(thesaurus)
'daring to go topless' is the wordplay.
'daring' becomes 'bold' (I've seen this before).
'to go topless' means to remove the first letter.
'bold' with its initial letter removed is 'OLD'.
(Other definitions for old that I've seen before include "Vintage" , "Senescent" , "Long-established" , "Getting on" , "No longer young" .)
