Long Cocktail Dresses

Empowered aesthetics are elongated with an astute approach for the after-dark edit of long cocktail dresses. Coded with timeless occasionwear principles (and reimagined with a refreshingly modern vision), the long cocktail dresses of this collection are crafted from a series of extra-special compositions. Show-stopping pieces appear in silky satin twill, structured crêpe, and flowing organza, offset by sculpting jersey, jacquard, and four-way support Compact Stretch. From slinky long black cocktail dresses to a considered palette of rich jewel tones, bold brights and refined neutrals, expect unique details (including feather cuffs, sequins, floral jacquard, embroidery, and embellishments) on a series of silhouettes. Find your piece from concise column cuts to long cocktail dresses with sleeves.
