Suggest, in a feeble manner, going topless (5)
I believe the answer is:
Here is my best explanation:
'suggest' is the definition.
(implying is a kind of suggesting)
'in a feeble manner going topless' is the wordplay.
'in a feeble manner' becomes 'limply'.
'going topless' means to remove the first letter.
'limply' with its initial letter taken off is 'IMPLY'.
