Etiquette experts love telling us what we should and shouldn't be doing. Whether it's where we should be holidaying, what we should be eating, or the items we should have in our kitchen cupboards - the internet is littered with a whole guide of how to behave 'properly'.
As with many things, the advice should always be taken with a pinch of salt - because who really likes being told how they should act all the time?
Most recently, The Independent spoke to national etiquette expert Diane Gottsman about how you should behave at someone else's wedding, and the three rules she thinks you absolutely can not break.
You shouldn't wear white
But you probably knew that already, didn't you? The rule scrawled across wedding invites everywhere in invisible ink is that wedding guests shouldn't wear white - unless for some reason they're told to. "White is still reserved for the bride," Gottsman told said.
You shouldn't take children if the invite says no children
The etiquette expert says the bride and groom should alway come first at their wedding - even if it means compromising on your own plans. Yes, you'd probably prefer to bring your children if it means saving on childcare, but if the wedding party plan on the event being child-free, try to keep it that way. "Guests should honour the request," she says. Consideration should be made for those breastfeeding, though.
You shouldn't propose or be proposed to
Nobody wants to have their thunder stolen, especially on such a special (and expensive!) day. As the etiquette expert says, "the celebration should be reserved for the bride and groom. Unless agreed-upon by the bride and groom in advance, any other celebration should wait for another time."
So next time you're planning on attending a wedding, make sure you're child-free, not wearing white, and aren't about to become a fiancée yourself.
