Midi Cocktail Dresses

Merging codes of elegant eveningwear with an innate understanding of modern design, the midi cocktail dresses in our edit are an unforgettable curation of signature silhouettes. Crafted for a lifetime of event styling, the midi cocktail dress appears in a series of elevated textiles — think silky satin twill, structured crêpe, and flowing organza, offset by sculpting jersey, jacquard, and four-way support Compact Stretch. With streamlined black midi cocktail dress options offsetting bold brights, regal reds, rich jewel tones, and refined neutrals, expect intricacies such as artful embroidery, scintillating embellishments, and structured panels. From ball occasion codes to midi cocktail dress for wedding fits, find yours below.
