Further work of tailor, at ease about finishing touches of fancy apparel (9)
I believe the answer is:
restyling
'finishing touches of fancy apparel' is the definition.
I can't tell whether this definition defines the answer.
'further work of tailor at ease' is the wordplay.
I cannot really see how this works, but
'ease' could be 'rest' ('rest' can be a synonym of 'ease') and 'rest' is located in the answer.
This explanation may well be incorrect...
'about' is the link.
Can you help me to learn more?
(Another definition for restyling that I've seen is " Creating new image".)
