What are some examples of symbolism in the story and what is the story's theme?

Some of
the examples of symbolism in "" are:  The necklace is a symbol of wealth and power for
Madame Loisel.  This represents a world she longs to be in but will never be able to reach.  The
apartment that she lives in with her husband is a constant reminder of what she feels is a
miserable life that she doesn't deserve and that she was not born to.  Another symbol is the
sholder wrap her husband went to put on her shoulders after the reception which again was a
reality check as to who she really was and her social class in life.  She was ashamed to have
her husband put it on her with the beautiful dress and necklace she was wearing.  It was a total
contradiction of who she was trying or posing to be.
