Camilla is usually not this ostentatious. These jewels are wearing/overwhelming her.
As I remember the story Camille's power as the #1 prostit...er...courtesan was being challenged by a new, younger, beautiful lass.
The younger version was going to make her claim to the title at some big to-do: She wore every fantastic piece of jewelery she'd been "gifted with" to show how appreciated she was.
To show her up, Camille walked downstairs into the party wearing a simple black dress with NOT ONE PIECE OF JEWELRY on...but behind Camille walked her maid--wearing all of Camille's jewels.
It seems that Cammy, II didn't learn a thing from her namesake...
