The protagonist of the story is Mathilde Loisel. The antagonist can either be describe as her bad luck, greed, and pride or, some say, it could be describe as her friend Madame Forestier since she didn't tell her that the necklace was invaluable in the beginning. It depends on how the reader interprets the story.
Madame Loisele is the protagonist, because she is the main character and the one with the conflict to overcome in the story. She wanted to impress everyone but instead she found out that the rich are not as careful at spending money as she is. She wanted to be a member of high class society even though she was not. She borrowed what she thought was an expensive necklace to prove that she belonged in high society. Then she lost it and lied about it to cover up the loss and wound up paying for her false pride and dishonesty by spending years in poverty paying for a necklace that was practically worthless.
Mme Loisell, who borrows the thing from her (friend) Mme Forestier- which means Forester. Parks would not be a bad translation. In a sense MMe Forestier is the antagonist, though fatal pride- and maybe alcohol played a role. I think she ( Loisell) was drunk when she lost the necklace at the party.. and waited too long to report it... that would explain why she did not call up MMe Forestier when she first noticed the item ( which she believed to be worth 60 Grand plus) was missing.
