Decorative style in gold backed by Chanel (6)
I believe the answer is:
rococo
'decorative style' is the definition.
'rococo' can be an answer for 'style' (I've seen this before). I'm unsure of the 'decorative' bit.
'gold backed by chanel' is the wordplay.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'backed' says the letters should be written in reverse.
'by' says to put letters next to each other.
'chanel' becomes 'coco' (I've seen this before).
'or' back-to-front is 'ro'.
'ro'+'coco'='ROCOCO'
'in' is the link.
Can you help me to learn more?
(Other definitions for rococo that I've seen before include "Elaborate baroque style of ornamentation" , "More elaborate form of baroque" , "Florid style" , "Ornate style of decoration." , "Grotesque" .)
