Revealed: The 20 Worst Wedding Faux Pas

By  | 

The most offensive and inappropriate wedding behaviour has been revealed in a recent survey conducted by high street fashion chain Jacamo. According to the guests asked, there a some surprisingly easy mistakes to make at a wedding and it’s likely you could be guilty of one of them!

Top of the list was a tasteless best man’s speech, which won’t help those who are already nervous about with the responsibility on the big day. Over a third of those surveyed revealed they had been witness to dodgy speeches that included mentioning ex’s and confessing cringe-worthy behaviour.


People considered the second worst wedding faux pas to be leaving before the end of reception speeches. It turns out exiting early could really put you in a bad light, despite how long and tiring the day is.

Unsurprisingly, fashion fails appeared several times on the list. Whether it be wearing all white or black, blocking the view with an oversized hat or turning up in jeans, there are a number of ways your outfit choice could put you on the ‘bad guest’ list.


Highest on the list of fashion faux pas and third in the entire list was wearing an overly-revealing outfit. On the other hand, overdressing for the occasion was also an offence, as was dressing like a bridesmaid. Aggressive Dad dancing and overenthusiastic bouquet-catching were also on the list, along with causing a scene after one too many drinks.
