Backless Prom Dresses
Elegant profiles define the backless prom dresses edit, merging timeless occasionwear codes with 2025’s leading trends for an unforgettable effect. The backless prom dress appears in a series of mini, maxi, and midi cuts, realized from luxury textiles for remarkable quality. The open back prom dress appears in contoured versions, with jersey, ponte, scuba, satin, crêpe, and the unparalleled four-way support of our iconic Compact Stretch. You’ll also find low back prom dress pieces that appear in tactile tulle, organza, chiffon, voile, georgette, silk and satin. Offsetting the open back, you’ll find corset-inspired bodices, dramatic puffed sleeves, mesh-trimmed cutout styles, halterneck cuts, and asymmetric necklines in a considered palette — with red and black tones offsetting captivating brights, classic neutrals and jewel tones.
