Hesitated, topless, getting changed (7)
I believe the answer is:
altered
'changed' is the definition.
(similar in meaning)
'hesitated topless' is the wordplay.
'hesitated' becomes 'faltered' (faltering is a kind of hesitating).
'topless' means to remove the first letter.
'faltered' with its initial letter taken off is 'ALTERED'.
'getting' acts as a link.
(Other definitions for altered that I've seen before include "Metamorphosed" , "Different" , "Reformed" , "Converted" , "Changed, adapted" .)
