Maybe you’re channeling classic Hollywood with a dramatic train, going full-on glam with shimmering embellishments, or keeping it sleek and modern in a curve-hugging number that’s all about that “less is more” energy. The best part? These dresses don’t just serve for prom night. They’re made for every epic photo op, every dance floor twirl, and every memory you’ll replay with your besties for years to come.
