Change name about fashion (7)
I believe the answer is:
restyle
'change name' is the definition.
The definition suggests a verb in its base form which matches the answer.
'about fashion' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'fashion' becomes 'style' (synonyms).
're'+'style'='RESTYLE'
Can you help me to learn more?
(Other definitions for restyle that I've seen before include "Remake in a new form" , "Of hair, shape in different fashion" , "Give a makeover to" , "Fashion anew" , "Modify" .)
