In "The Gift of the Magi," the irony is that Della had cut off her hair to buy Jim’s gift. She sells her beautiful hair to buy a chain for Jim's watch, while Jim sells his watch to buy Della the combs for her hair. This mutual sacrifice highlights the depth of their love, but it also leads to the poignant irony of their gifts being rendered useless.
