Present topless chest (5)
I believe the answer is:
offer
'present' is the definition.
(thesaurus)
'topless chest' is the wordplay.
'topless' means to remove the first letter.
'chest' becomes 'coffer' (coffer is a kind of chest).
'coffer' with its initial letter removed is 'OFFER'.
(Other definitions for offer that I've seen before include "Proposition" , "Suggest" , "Expression of willingness to pay or give" , "Volunteer, present" , "Propose; make available" .)
