Long Prom Dresses

Elongated lengths of elegant long prom dresses mark the 2025 season with unparalleled aplomb. The long prom dress appears in a series of luxury textiles, spotlighting our dedication to premium design. Expect ethereal textiles that layer for exaggerated depth, such as tulle, organza, chiffon, voile, georgette, and chiffon, alongside slinky styles that drape with fluid mastery — including satin, silk, lace, jersey, linen, and taffeta. You’ll also find contouring pieces that create a bespoke fit from form-fitting jersey, jacquard, and the four-way support of our iconic Compact Stretch. The monochromatic depth of the long black prom dresses appears alongside a considered palette of color, with long red prom dresses, bold brights, regal reds, rich jewel tones, and refined neutrals aplenty.
