Ornate baroque style (6)
I believe the answer is:
rococo
'ornate baroque style' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for rococo that I've seen before include "Elaborately ornate" , "Florid style" , "Fanciful decoration" , "Delicate architectural style from 18th-century France" , "Eighteenth-century French architectural style" .)
