The ultimate guide to wedding guest etiquette (or how not to make your friends hate you)

Can you wear black? Can you bring a plus one? What about inviting kids? Jessica Salter dissects the most common wedding guest dilemmas

All dolled up, my boyfriend and I turned up at a ceremony north of Watford, at the punchy time of 9am. The groom - my boyfriend’s university friend - gave us a quizzical look, which we put down to nerves. We enjoyed a full day of celebrations: an English ceremony, then an Indian one (both of which made me cry, despite being the plus-one), lasting well past midnight. It was only weeks later that it emerged we had been invited as evening guests. The fact the couple had seamlessly merged us into their day without us noticing says a lot about their classy style. But the wedding faux pas still haunts me.

 

Mine might have been unintentional, but I’ve heard of some other shocking wedding guest etiquette fails over the years. Like the mother-of-the-bride, proud of her recent body transformation, who wanted to wear her own wedding dress to her daughter’s big day. Or the sister-in-law who missed half the meal because she was getting changed into her third (very low-cut) outfit of the day. Or the guest who switched place cards at the meal, moving the bride to sit next to him instead of her bridesmaid.

 

Of course, these are all big no-nos. But the truth is that most wedding etiquette is not really about rules. It's about reading the room - or more accurately, the couples’ wishes. A black gown at a black-tie evening wedding? Elegant. But the same one at a daytime garden ceremony in June? Maybe, but it’s worth thinking twice - because your outfit shouldn’t dominate conversation. The same logic applies to white: a floral print on a white summer dress sounds delightful, but a stark, head-to-toe ivory situation - well, you already know the answer.

The plus-one question is where things get thorny, mostly because it carries a financial burden. This isn’t a kitchen supper party where one extra body is no great shakes. It’s an occasion where cost-per-guest is around £300, according to current estimates. If you’re worried about who you’ll be sitting with, it’s okay to ask about seating arrangements. But it’s likely you’ll have a band of mates around you, or if not, remember that weddings are typically friendly functions.


Children, much like plus-ones, are only welcome if explicitly invited - although if you have a babe in arms, it’s probably okay to ask. Sure, costs are less of an issue - babies don’t tend to knock back booze and canapés - but kids change the vibe, and not always in a welcome way. 


If these are the biggies, then there are the smaller dilemmas. Do you need to bring a gift, even if the whole weekend abroad has cost a fortune? Yes, that’s part of the deal. If the couple in question has said no gifts, respect that, but maybe consider a gift voucher for a fancy restaurant instead. And about moving the place card - technically, this is a no. Someone has likely spent hours mentally jiggling those around like a game of wedding Tetris. On the day, however, a subtle rearrangement at a lower tier table will probably go unnoticed.


What it all comes back to is something very simple: weddings are not about the guest. They’re a rare opportunity to celebrate love and joy. This mindset applies to the happy couple, too - the more you accept that a room full of people from different chapters of your life will inevitably have its quirks, the happier you’ll be. 


Just like the couple who gracefully made me feel welcome at their entire wedding all those years ago.
