Maxi Prom Dresses

Elegant lengths are the epitome of the 2025 prom season, as demonstrated by the maxi prom dresses collection. Below, you’ll find floor-length iterations of maxi prom dresses, crafted from a series of premium textiles that spotlight our dedication to luxury craftsmanship. Think languid silk, elegant linen, flowing chiffon, and cascading organza materials that are contrasted by form-fitting textiles — such as knitted jersey, structured crêpe, woven jacquard, and the four-way support of our revered Compact Stretch. The black maxi prom dress appears alongside rich red colors, soft pastels, bold brights, refined neturals, and jewel tones aplenty. With puffed, angel, wide, draped, and asymmetric sleeves to consider, the long sleeve maxi prom dress edit has it all.
