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.

Tailored Compact Stretch Viscose Cape Mesh Panel Midi Dress
Dramatic floor-length cape panels extend from the shoulders, creating a sweeping, architectural silhouette that commands attention from every angle Sheer mesh inserts at the sides offer a refined contrast in texture, adding dimension to the otherwise sleek, tailored body of the dress Compact stretch viscose construction ensures a precisely fitted, body-skimming shape that moves with ease and retains its form throughout wear A front midi-length split introduces graceful movement and a considered sense of proportion, balancing the drama of the cape with understated elegance Clean bateau neckline and structured shoulders reflect expert tailoring, lending the silhouette a sharp, contemporary edge This cape midi dress is a masterclass in occasion dressing, designed for the woman who understands that true sophistication lies in considered construction rather than excess. The elongated cape panels create an effortlessly dramatic entrance, making it an exceptional choice for black-tie events, gala evenings, and formal weddings where a refined statement is called for. The tailored fit through the body ensures a polished, composed look, while the front split and mesh detailing introduce just enough intrigue to keep the silhouette feeling thoroughly modern. Style as the model does, pairing with pointed-toe court heels and statement drop earrings to let the architectural lines of the dress take centre stage. For a finishing touch, opt for a sleek, swept-back updo to honour the clean neckline and allow the cape to flow uninterrupted. This is a dress that speaks with quiet authority - ideal for race days, graduation ceremonies, or any occasion that calls for impeccable, considered dressing.
