Long Party Dresses

The elegant appeal of the maxi dress is updated with after-dark drama to create this modern edit of long party dresses. Below, you’ll find a series of elongated silhouettes that are crafted from premium textiles that appear in a palette of party-ready tones — think bold brights, refined neutrals, sleek monochromatics, considered pastels, and zesty citrus. With a series of necklines (scoop, bandeau, asymmetric, square, straight, and halter), sleeves (such as puffed, angel, draped, cape, and cap), and skirts (column, A-line, slip, slanted, and tiered), our long party dresses for women are shaped from a series of compositions. Think sculpting jersey, jacquard, and the four-way support of Compact Stretch (creating a bespoke fit with four-way stretch), and flowing styles that are cut from satin, silk, lace, jersey, chiffon, organza, and taffeta. Our maxi party dresses are enlivened with artful touches that will incite an imaginative essence in your late-night ensemble. Think intricate embroidery, dynamic tassels, scintillating sequins, gathered rosettes, tactile feather trims, ornate lace panels, scalloped hems, and appliqué details aplenty. Shop long dresses for a party below.
