Midi Party Dresses at M&S

Step onto the dance floor with one of our dazzling women’s party midi dresses, part of our wider women’s partywear edit. Cocktail soirées, festive gatherings and glamorous nights out are all covered here, with options from much-loved womenswear labels like Monsoon and Ghost. Crafted in luxe fabrics like velvet and satin, and adorned with shimmering sequins or metallic threads, our ladies’ party midi dresses are on hand to help you pull out all the stops.

When you’re shopping for a special occasion, look for midi dresses with tailored cuts and flowing silhouettes that are designed to flatter your figure – and look great on social media, too. Sleeveless and strappy designs add a summery edge, while long-sleeved midi dresses bring elegance and coverage if it’s a little chillier. Choose bold floral prints and dramatic block colours – think richly hued blue dresses and crisp white dresses – for a touch of variety. Whether you prefer a classic A-line, a fitted shift or something with tiered ruffles, there’s a style to suit every shape and setting in our wider dress collection.

Chosen your new fave? For even more wow, pair your women’s party midi dress with sleek high-heel shoes, chic women's clutch bags and sparkling accessories like women's necklaces and earrings. Looking for other options to dial up the glamour? Check out our full selection of party dresses for statement pieces in mini, midi and maxi lengths.
