Are there any foreshadowing, flashbacks in the necklace? Are there any similes and metaphors?

Flashback – “But sometimes, when her husband was at the office, she sat down by the window and thought of that evening long ago…”

Foreshadowing – Madame Forrestier easily lends her the necklace. The jeweler says, “It was not I who sold her the necklace, I merely supplied the clasp.”

Metaphor – “She seemed to float through a cloud of happiness.”

“she danced madly, drunk with pleasure.”

Simile – “One of those old night-prowling carriages which are only to be seen in Paris after dark, as though they are ashamed.”
