Opulent, sumptuous (6)
I believe the answer is:
lavish
I believe this clue is a double definition.
'opulent' is the first definition.
(I've seen this in another clue)
'sumptuous' is the second definition.
(I've seen this before)
(Other definitions for lavish that I've seen before include "Extremely generous" , "Luxurious" , "Generous - liberal" , "Plentiful or munificent" , "Prodigal - unrestrained" .)
