What to Wear to a Wedding: The Harrods Guide to Wedding Guest Dress Codes

Words by Sophia Miller

Wedding dress codes are one of the great ambiguities of life. What should you wear to a black-tie ’do? Do you have to wear a hat? And what are the best wedding guest dresses for sticky summer weather? We’re here to help. Learning the subtle nuances that define each occasion – from topiary-lined English gardens to see-and-be-seen city receptions – is a good place to start your outfit planning as the invitations stack up.

What to Wear to a Black-Tie Wedding

The black-tie dress code is reserved for the most elegant occasions in the social calendar – but what does it actually mean? In summary, it calls for women to wear a long (often floor-length) dress or gown, fashioned in an evening-appropriate material such as silk or chiffon – think your most special finery. Sometimes a slightly shorter ankle-length or cocktail dress suits, but anything above the knee will likely steer you into too-casual territory – but a high-low hemline could be a clever way around it. Just remember: when black tie is written on the wedding invite, you should take it as an opportunity to really dress up.

What to Wear to a Formal Wedding

Sometimes referred to as ‘black tie optional’, you can think of a formal dress code as one step below the sophistication of black tie. A smart midi- or full-length dress or a tailored suit with an air of elevation are ideal. The location and time of the wedding can play an important role in the kind of outfit you choose – English country weddings designated as formal may invite bright colours, florals and a hat or fascinator, whereas glossy city receptions offer the opportunity to experiment with bold silhouettes, darker hues or more cocktail-esque dresses.

What to Wear to a Wedding with a Cocktail Dress Code

If a wedding invite specifies a cocktail dress code, it’s likely to be a stylish affair – but without the more rigid constraints of formal or black-tie attire. Here is where you can experiment with cocktail dresses, jumpsuits or two-pieces in different colours, patterns or materials, so long as the overall result remains smart and evening-appropriate. Floor-length gowns will be too formal here, so stick to your usual wedding-guest repertoire.

What to Wear to an Outdoor Wedding

The country wedding is a quintessentially English affair, and one with a charm that’s hard to beat. When it comes to choosing what to wear to a garden wedding, lean into your surroundings and opt for bright details and prints – florals are the stereotypical choice for good reason, but stripes, polka dots and lace detailing are equally well-suited. If the hosts lean traditional, you can choose to wear a hat, but otherwise, outdoor weddings often necessitate slightly less formal and more daytime-appropriate attire – think cotton and silk rather than brocade, feathers and heavy embellishments. Lastly, if you’re likely to be spending time on grass or gravel, think about choosing a block heel over spindly stilettos to ensure steady footing.

What to Wear to a Beach Wedding

Destination weddings are rarely more idyllic than when the ceremony takes place right on the beach – but it can be tricky to know what to wear when your usual holiday wardrobe revolves around swimwear. Warm temperatures mean that flowing silhouettes and breathable materials are key – think silk, linen and lightweight stretch knits, while tropical surroundings lend themselves to both bold patterns and fun, textured accessories (raffia, shells and pearl are all invited). Flat sandals are a smart choice if you’ll be directly on the sand – and don’t forget a pair of sunglasses.

Your Questions Answered

It all depends on the specific wedding you’re attending. Different dress codes, venues and couples require different approaches, so pay attention to your invitation – and always ask if you’re unsure. It goes without saying that guests should avoid white unless otherwise specified, and it’s always safer to err on the side of modesty, so as to ensure the newlyweds have their moment in the spotlight.

Today, the most stylish wedding guest outfits come in all manner of colours – and few are truly off-limits. If, like at many weddings, the bride will be wearing white, be sure to avoid the lighter shades of the spectrum (including creams, off-whites or even ultra-pale yellows). Though some traditional advice decrees that wedding guests also avoid wearing red and black, it’s less taboo to choose these shades at most modern weddings – though the very wary may choose to err on the side of caution.

The matter of whether to wear black to a wedding can be contentious – and often, the answer will depend on the attitude of the hosting couple. These days, black is usually a perfectly acceptable choice and has the benefit of being easy to accessorise and wear again for different occasions. However, a formal English country wedding might require a little more respect for tradition, so always consider whether your outfit will look appropriate at the venue in question.

Yes, definitely – in fact, choosing an outfit with a print or a pattern is a great way to express your personal style when attending a wedding. Florals, stripes or polka dots are always a good option for summer occasions, while more glamorous cocktail receptions or city weddings are a time to bring out even bolder patterns, metallics and sequins. It may be wise to avoid white-based patterns to avoid competing with the bride.

Midi- and maxi-length dresses are a fail-safe choice for summer days – but make sure to check the dress code, as certain religious venues may prohibit bare shoulders or shorter hemlines. Equally, when the sun is shining, feminine prints like florals and polka dots, or bright block colours and pastel hues, look right at home. On the accessories front, look to lawn-proof block heels over stilettos as you’re likely to spend some time outside.

Absolutely – in fact, the most formal of British summer-wedding dress codes specifically request that women wear hats. Choose a headpiece or fascinator that coordinates with the rest of your outfit, and take care not to opt for anything too large that might obstruct other guests’ view of the ceremony. Make sure to also properly secure your hat to your hair to avoid any wind-related mishaps!

If a dress isn’t your usual style, don’t feel you have to wear one to a wedding – there are plenty of equally chic alternatives at hand. If the dress code requires something below the knee, try a jumpsuit or a tailored trouser suit for an effortlessly stylish look that borrows from the world of menswear. Alternatively, more casual wedding dress codes suit co-ords or two-pieces made up of skirts, trousers or even shorts.
