The Harrods Guide to the Cocktail Dress Code for Women

Words by Sophia Miller

Cocktail dressing: the confusing catch-all phrase that has the potential to strike fear into even the savviest style mavens. Whether it’s a wedding, garden party or drinks reception, a cocktail event usually suggests a level of formality – but not quite that of black tie. No full-length gowns required here. So, what length of dress should you choose? Do you even have to wear a dress? And how do you predict how smart an event will be?

Look no further for the ultimate guide to navigating the cocktail dress code for women, informed by some of fashion’s leading partywear experts. RSVP in confidence.

Popularised in 1920s America, then pioneered in later decades by the likes of CHANEL, Schiaparelli and Dior, the cocktail dress code refers to semi-formal attire usually worn in the late afternoon or evening. While mid-century tradition dictated a calf-length dress – perhaps paired with a matching nipped-in jacket – today’s options are far broader. Mini and midi dresses are now de rigueur, with the term ‘cocktail dress’ usually suggesting a party-appropriate piece of either length that’s sophisticated without being stuffy. Elsewhere, co-ords, jumpsuits and tailored separates are equally chic options for those who prefer not to wear a dress – or, who need a little day-to-night versatility in their wardrobe.

“‘Cocktail dressing’ means it’s time to show up and have fun,” says designer and brand founder Edeline Lee. “Most of our pieces can slide straight from work and life into cocktail mode: strong enough to be listened to in a boardroom, but playful enough to shine at a party.”

“Modern occasionwear has fewer rules,” explains designer Emilia Wickstead. “A sense of simplicity and ease is key, regardless of the silhouette. Good fit and construction make the difference.” Edeline Lee agrees that you should choose the outfit that makes you feel comfortable and confident, adding that “colour can be a deciding factor: choose something bright if you want to stand out, or a neutral if you’re feeling more discreet.”

If you’re looking for more specific guidelines, designer Magda Butrym suggests striking a balance between playful glamour and modern sophistication. “Our signature floral-appliqué dresses in luxurious silk and sharply tailored pieces in classic black always stand out at cocktail events,” she says.

As the dress code with the most leeway for creativity, cocktail RSVPs offer the opportunity to have fun with your accessories. Embellished heels, colourful clutch bags and dramatic costume jewels are encouraged, and can bring a dose of personality to your outfit. The moment may also be right to don a wow-factor hat or fascinator.

Take it from the experts: “My go-to is a beautifully crafted dress paired with sculptural heels – simple yet impactful. Then, on days when I don’t feel my best, I opt for an oversized suit accented with statement earrings,” says Magda Butrym.
