I'm a wedding expert - here are 5 common mistakes that will make you a bad guest at your friend's big day

Weddings are magical celebrations of love, laughter, and happily-ever-afters - but for guests, navigating the big day can feel like walking a tightrope of unspoken rules and expectations. 

Between dodging the bride's train on the dance floor and debating whether it's okay to post that perfect cake-cutting photo to Instagram, being the ideal wedding guest carries certain responsibilities on the special day. 

Angela DeMaio, wedding etiquette expert at US-based Bouquet Casting Co, knows all too well of the blunders even well-meaning guests can find themselves committing.

The expert shared with the Manchester Evening News her insight into five common guest mistakes - and how to avoid them.

Ignoring seating arrangements 

One of the most common blunders guests make is ignoring the seating plan. 

It might seem harmless to switch seats or sit wherever you feel comfortable, but this can disrupt the couple's carefully planned arrangements.

DeMaio said: 'Seating arrangements are often crafted with thought, considering relationships and group dynamics.'

According to the expert, ignoring seating plans can disturb the balance the couple has tried to create. 

To respect their efforts, it's important to be mindful of where each guest is seated.  

If you're unsure about your seat, don't hesitate to ask the host for clarification rather than assuming a spot.

Getting in the photographer's way

Weddings are a once-in-a-lifetime event, and the photographer's job is to capture precious moments from the couple's big day. 

However, eager guests sometimes get in the way, blocking the shot or stepping into the aisle at the wrong time.

According to DeMaio, guests should especially avoid stepping into the aisle during the processional or standing in the way of key moments, such as the couple's first dance. 

Being patient and respectful of the photographer's space ensures the couple gets the perfect shots without disruption. 

The expert also encourages guests to wait until the photographer has finished their work, and be mindful to let the couple share their photos first. 

Having one too many at the open bar

While many guests look forward to the open bar, moderation is key to ensuring the evening stays enjoyable for everyone. 

Nobody wants to be remembered as the guest who had too much to drink and caused a scene.

DeMaio warned: 'Weddings are joyous occasions, but they're not the time for drunken antics or behaviour that distracts from the couple's special day.'

She urges guests to pace themselves with water in between alcoholic drinks, and to remember to stay respectful to other guests and staff.  

Not saying goodbye

As the night winds down, it's easy to slip out early, especially after a long day of celebration. 

However, failing to acknowledge the couple before leaving can come across as rude or dismissive.

DeMaio suggested: 'If possible, thank the bride and groom in person for the invitation, as it's a small gesture that goes a long way.'

For those who need to slip out early from the event, the expert suggests being discreet, and ensuring you've expressed your appreciation to the couple at some point during the day. 

Leaving without acknowledging the couple can leave them wondering if you truly valued the celebration.

Posting pictures to social media without permission 

In the golden age of social media, it's tempting to share every moment of the wedding, but this can lead to unintended consequences.  

As the big day is deeply personal, most couples prefer to have control over when and how their wedding photos are shared, so discretion is key. 

According to DeMaio, it's crucial for guests to wait until the couple has posted their own photographs before sharing anything.

For weddings with a phone ban, guests are advised to be respectful, as you may risk upsetting or irritating the newlyweds by sneaking photos you've been asked not to upload.
