Black Prom Dresses UK: Long, Short, Lace & Sequin Styles

Shop black prom dresses in long and short styles, from sequin and lace to mermaid and corset. Every HappyProm dress is made to your measurements, with free custom sizing.

▼ Why Black Prom Dresses are the Ultimate Style Statement

Black is a classic prom colour: formal, easy to accessorise and available in every shape. Whether you want a sequin gown that catches the light, a lace corset dress or a sleek mermaid, there's a style for a Year 11 prom, a leavers' ball or a black-tie event. Browse by length or detail: long prom dresses, short prom dresses, lace, sequin, mermaid, corset, with sleeves and plus size.

Made to your measurements

Every black dress is made to order with free custom sizing, so you aren't choosing from a standard size chart. We generally need your bust, waist, hips and height with your shoes on, and we add 2–3 cm of extra room to every dress. See how to measure for a prom dress.

Order in good time

Because each dress is made to order, order about nine weeks before prom in busy season. Rush making is free, but please contact us first. See when to buy your prom dress.

Not sure how to style it?

Gold or silver jewellery, a bold lip, a coloured clutch or a wrap can change a black dress completely. Our guide to black prom dresses covers styles, makeup and accessories, and our prom dress trends for 2027 shows what's new.
