The grandmother’s hat, which she wears for the sole purpose of showing that she is a lady, represents her misguided moral code. When the grandmother prepares for the car trip with the family, she dresses up to be prepared for a car accident so that anyone seeing her dead body would know that she’d been a lady. The grandmother seems to be entirely unconcerned with the fact that she’s dead in this scenario and oblivious to the fact that other people—including her three grandchildren—would have probably died as well. For the grandmother, the only thing that matters is her standing as a lady, a ridiculous concern that reveals her selfishness and flimsy moral conviction. When the grandmother does become involved in a car accident, the hat—like her moral convictions—falls apart. After she is thrown from the car and the family is facing the Misfit, the brim of the hat falls off. She drops the broken hat as her self-conception as a lady dissolves.
