Prom deserves a dress you'll still like looking at in ten years. These are our floor-length styles with the drama turned up — corset bodices for structure and support, crystal and sequin embellishment, appliqué detail across fitted and full skirts alike. The corset styles are worth singling out: boning through the bodice means the dress stays where you put it, which matters across a long evening of photographs. Silhouettes range from column to full skirt, so there's something whether you want to glide or to sweep. Order with time for alterations — hemming to your exact heel height is the single change that makes a formal dress look properly expensive.
