Opulent means richly and showily luxurious. An opulent interior, opulent fabrics, opulent and gilded.
The showiness is part of it — opulence is wealth on display, which is why the word suits hotel lobbies and palaces and not quiet good taste. It is nearly always about surroundings rather than people. Note that the Latin ops means wealth and resources, the same root as opera and copious.
