Good character names?

what would be a fitting name for a character of this description?

'She had long, dark hair tied up into a bun with a few jewelled pins sticking out of it. She was wearing a frilly, purple dress, golden necklace, a few rings and sparkly knee-length boots. She was also wearing elbow-length gloves and gold earrings with amethysts set in them. She had a small petite nose and delicately pointed ears. But there was nothing girlish and cute about the expression on her face. Her voice was smooth and slippery, like a snake’s and not to be trusted. '
