What is the foreshadowing in the story?

There are several elements of foreshadowing in the wonderful story "The Necklace."

Start with the opening line: "The girl was one of those pretty and charming young creatures who sometimes are born, as if by a slip of fate, into a family of clerks."

This lets us know fate will play a role, that slips will play a role, and that she really should look like a clerk, as she does by the story's end.

 

The first line of the second paragraph says why she dresses plainly; this is stated almost as a universal, and it will be true again by the end of the story.

 

A bit later, the story says, " She had no gowns, no jewels, nothing. And she loved nothing but that." This is foreshadowing through irony. She loves only that—and it will be taken from her.
