Excessively decorated (6)
I believe the answer is:
ornate
'excessively decorated' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ornate that I've seen before include "Elaborately decorated, perhaps overdone" , "Highly embellished" , "Sumptuously decorated" , "Ostentatious" , "Heavily decorated" .)
