Long Sleeve Prom Dresses

Mark the moment with a considered and contemporary edit of long sleeve prom dresses. Celebrating the start of a new chapter, this curation of long sleeve prom dresses appears in a bold and beautiful palette of colour — with the timeless mastery of the black long sleeve prom dress offsetting a characterful canvas of bold brights, regal reds, rich jewel tones, sleek monochromatics, earthy greens, aquatic blues, and refined neutrals taking the spotlight. Artfully enlivened with luxurious touches, the silhouettes in our edit feature modern detailing such as intricate embroidery, dynamic tassels, scintillating sequins, gathered rosettes, and tactile feather trims. Find your bespoke fit in our long sleeved prom dresses with floor-length, midi, and mini cuts all boasting a myriad of fits. With angel, cape, wide, puffed, and compact long sleeves to find, this edit is carefully composed with a series of necklines (from Bardot and bandeau, to scoop neck and plunging versions), to skirts (slip, A-line, asymmetric, and tiered). Ready to be styled with soaring stilettos and polished hair for a classic effect, find your custom fit below.
