What to wear to a wedding: Dress codes explained & outfit ideas

From black tie to smart casual, we've got the lowdown on what you should wear to a wedding and how to advise guests on your own wedding dress code.

Choosing what to wear to a wedding used to be simple: full-on formal all the way. Think pastel dresses with matching jackets and hats, and the smartest of suits. When it comes to 2020 wedding guest dressing, however, the rules aren’t as obvious.

Of course, some traditionally-minded couples will include a dress code with their invitations. This can make life easier, as you at least have a steer on what to wear, but it can also be somewhat panic-inducing if you aren’t sure exactly what it means.

If there’s no dress code included in the invitations, you’ll still want to dress to suit the wedding style – you might feel out of place in full-on sequins and killer heels at a boho countryside celebration, for example. It’s easiest to ask the couple what sort of wedding they’re having and build your outfit from there. But if for any reason you’re not keen on doing this, check out their venue online to get an idea.

To make your wedding guest outfit hunt more enjoyable, we’re going to explain exactly what the most common traditional dress codes really mean. We’ll also reveal the 2020 style rules for wedding guests – and show you our favourite looks to buy right now. All you’ll have to worry about is what to write in the wedding card. Happy shopping!

What is a white tie dress code?

If you see this on a wedding invitation, the occasion will be extremely formal. Ladies should wear a full-length ball gown with optional gloves. Men should be dressed in an evening tailcoat (not a morning coat) with a white waistcoat and bow tie, high-waisted black trousers and black leather shoes. Top hats and white gloves are optional. Think Downton Abbey and you’re along the right lines!

What should I wear to a black tie wedding?

This is the second most formal dress code for weddings, usually held in the evening. Men should wear a black dinner jacket and bow tie, white evening shirt and black tapered trousers. Unless dress length is specified, ladies can choose a cocktail dress (fitted, to the knee), formal jumpsuit or trousers, or a full-length gown – this can be any colour.

What does black tie optional or formal mean?

This slightly confusing-sounding dress code means that while male guests can wear a dinner jacket, it isn’t obligatory. A dark suit and tie is a perfectly acceptable wedding guest outfit. Ladies can wear a long gown, a formal cocktail dress, or nicely cut trousers or jumpsuit.

What is morning dress?

You’ll normally see this formal dress code on an invite to a very traditional wedding. Men should wear a black or grey morning coat, striped or houndstooth trousers, waistcoat, collar shirt, black shoes, tie and an optional top hat. Women should opt for a chic, not too revealing outfit – we’re talking no slip dresses (unless worn with a jacket over the top) or ultra-short dresses.

What is a lounge suit?

This is another typically British wedding dress code. A “lounge suit” is simply a suit. It could be black or dark grey, with a white shirt and a smart tie, which doesn’t have to be black. For the ladies, any smart dress is perfect. A long evening dress would be over the top on this occasion.

What should I wear for a smart casual or semiformal dress code?

Don’t be fooled by the word “casual” here. The couple does not want you to arrive in jeans. Men should wear a suit and tie, but can take their jacket off later during the reception party if the groom and groomsmen lead by example. Women should go dressy, but it’s more about understated chic than full-on red carpet glamour.

What is a casual dress code?

Casual sounds like you’re allowed to turn up wearing anything you like. However, you should read “casual” the same as “casual Friday” at work. Jeans are not appropriate. Men should wear a button-down shirt and dress trousers, shoes can be brown. For women, we’d suggest a summer dress, or a pretty blouse with a skirt or smart trousers.

What is cocktail attire?

Cocktail attire usually means an evening wedding, but you should avoid looking like you’re going to a club. An elegant dress that’s neither too formal nor too casual is perfect. Men should stick to a dark suit and tie.

What do I wear to a beach formal wedding?

This tricky combination means you must look elegant, but also prepare for sand, wind, water and sun! Just imagine you’ve been invited to a smart beach-side restaurant on a summer’s day. Gentlemen should wear a linen suit or shirt with khaki or linen trousers. Smart leather sandals are perfect for him and no tie is necessary. Do avoid shorts, unless you’ve been told my the couple that these are acceptable. Female guests could consider a midi or maxi formal summer dress with flat sandals or wedges that are suitable for walking on sand.

What to wear to a wedding in 2020?

Follow our 6 up-to-date style rules to take your wedding guest look to the next level.

Rule 1. Patterns are your friend

The problem with wearing an outfit in one colour is that the bridesmaids may be in the same hue. This isn’t in itself a tragedy, but you might appear a bit recalcitrant to the other guests when you don’t walk down the aisle with the bride squad – and nobody wants to be The Bad Bridesmaid. The way to get round this is by going with a print. Florals are always popular, particularly for summer weddings, but this isn’t the only print in town – on-trend polka dots and abstract designs look just as good.

If you do go floral, make it feel fresh by choosing a contemporary silhouette – 2020 is all about sleeves and shoulders. Of course, the bride may choose floral bridesmaid dresses, but the chances of her picking the exact same style as your guest dress are slim; check with her if you’re concerned.

Colour blocking has been popping up on the catwalks, and is a chic way to avoid a head-to-toe hue if your style is too minimalist for patterns.

Rule 2. Consider a cover-up

Rule 3. Jumpsuits are perfectly acceptable

The all-in-one has been on the fashion scene long enough to be an elegant, established choice for a formal setting. After all, if you can get bridal jumpsuits now, why shouldn’t the guests follow suit? We’re still not entirely convinced by playsuits for a smarter celebration, even if nicely styled, but a jumpsuit? Go for it.

Lemongrass Jumpsuit – £300, Reformation

The shape of Reformation’s Lemongrass jumpsuit is so flattering: wide kimono sleeves balance a deep v-neck and nipped-in waist. We love the print, which is pretty without being overly floral.

Rule 4. Choose a micro bag

The micro bag trend is rather annoying in daily life (where, precisely, are we supposed to put our stuff?), but for a wedding, where you’ll hopefully need little more than keys phone and lipstick, it makes much more sense.

Rule 5. Black is fine, white is out

There’s been much debate about which colours are acceptable to wear to a wedding. We’d still recommend avoiding white, unless it has an extensive coloured pattern. Black, once considered unacceptable, is now perfectly fine for guests at contemporary weddings, although if in doubt, check with the couple. To avoid looking too sombre, choose a style where the colour is broken up – lace panels, mesh and glittering finishes all add a sense of lightness. If you do want a simple all-over-black outfit, statement accessories are a must. This is a joyous occasion – let your look reflect that, while still staying chic.

Sequin-Embellished Midi Dress – £252, Maje at Selfridges

All-over sequins mean this Maje dress will sparkle on the dance floor. The silhouette is simple but beautifully judged, from the dipped hem at the back to the v-neck.

Whoever designed this River Island dress is a genius. It would have been chic enough in a plain mesh fabric – adding the stripes makes it next-level elegant. We also adore that high ruffle neck.

Rule 6. Don’t dismiss flats

For the longest time, there was a generally accepted belief that heels were the only acceptable female footwear for a formal or glamorous occasion. Not any more. The fashion world’s love affair with flats and barely-there heels continues, which means there are plenty of beautiful options for party shoes that won’t leave the balls of your feet burning. As for high heels improving posture, we’re not convinced – so long as you walk tall in your flats or super-low-heels, you’ll be every inch the wedding guest goddess.

Silver Embellished Pointed Toe Sandals – £45, River Island

If it’s glitz you’re after, look no further. These River Island pointed-toe mules will add sparkle to any outfit, and the barely-there heel means you can razzle dazzle ’em in comfort.

We’ve long been in love with Valentino’s iconic Rockstud range, which spans a range of heel heights. We struggled to choose just one of the flats, but in the end, it had to be their patent leather mule in poudre. The delicate shade and chic shape contrast so wonderfully with the tough-girl studs.
