Black at prom is the grown-up choice, and it photographs better than almost anything under the lighting these evenings actually have. These are our black floor-length styles with the detail turned up — crystal and diamanté embellishment, appliqué across fitted and full skirts, corset bodices for structure, and strapless and long-sleeve shapes depending on the season. The corset styles are the ones to look at first: boning through the bodice means the dress stays where you put it across a long evening of photographs. Black also lets embellishment do all the work, so a crystal or beaded piece reads far more expensive in black than the same detail in a pale shade.
