Stopped going topless and relaxed (5)
I believe the answer is:
eased
'relaxed' is the definition.
(I've seen this before)
'stopped going topless' is the wordplay.
'stopped' becomes 'ceased' ('cease' can be a synonym of 'stop').
'going topless' means to remove the first letter.
'ceased' with its initial letter taken off is 'EASED'.
'and' is the link.
(Other definitions for eased that I've seen before include "Became less painful" , "Calmed" , "Moved carefully" , "Helped" , "Slowed down" .)
