We can admit to ourselves that a few of our formal dresses in high school might've made our family members want to cry . . . but not in a good way. But it's not a fashion faux pas that brought this grandma to tears — it was something much, much sweeter. Grandma Dottie gave her granddaughter a prom dress when she was a little girl for "dress up," and the dress stayed stored in a closet over the years. Cassie then decided to wear it for her senior prom night [1]. The adorably retro dress was worn by Dottie 57 years earlier, and she had no idea that Cassie was going to bring it back half a century later. Watch the big reveal and Grandma Dottie's tearful reaction.
