Chanel pursuing return of gold for artistic style (6)
I believe the answer is:
rococo
'artistic style' is the definition.
(I know that rococo is a type of artistic style)
'chanel pursuing return of gold' is the wordplay.
'chanel' becomes 'coco' (I've seen this in other clues).
'pursuing' is a charade indicator (letters next to each other).
'return of' says the letters should be written in reverse.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'or' back-to-front is 'ro'.
'coco' after 'ro' is 'ROCOCO'.
'for' acts as a link.
(Other definitions for rococo that I've seen before include "Delicate architectural style from 18th-century France" , "18th-century French style" , "Style of architecture, art, etc associated with the time of Louis XV" , "Late Baroque artistic style" , "With an ornately decorated style" .)
