Chic nurse's styling accessory (9)
I believe the answer is:
scrunchie
'accessory' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'chic nurse's styling' is the wordplay.
'styling' indicates anagramming the letters (I've seen 'styled' mean this).
'chic'+'nurse'='chicnurse'
'chicnurse' anagrammed gives 'SCRUNCHIE'.
Can you help me to learn more?
(Other definitions for scrunchie that I've seen before include "hair fastener" , "Circular band for holding hair back" , "Elasticated hair grip" .)
