When it comes to weddings, there are a number of unspoken rules that guests must stick to.
Whether it's showing up on time, not texting during the ceremony, never bringing an uninvited plus one, or at no point - unless instructed to by the bridal party - should anyone wear a white dress... ever.
But it seems that one guest didn't quite get the memo, as she decided to turn up in a white dress.
Taking to the Facebook group That's it, I'm Wedding Shaming, an unimpressed bride told all on how she got her sweet revenge.
In a note written by the bride to the guest, she starts by thanking them for attending the service - the calm before the storm - before addressing the elephant in the room.
She said: "It was an honour to share the entitlement of wearing a white dress with you" before ending the note with: "Best wishes". Savage.
The post received over 3,000 likes, with a number of people cheering on her sassy response, as reported by The Sun.
One person said: "Oh my god, the petty is amazing".
And another agreed: "Now, THIS is the type of passive-aggressive pettiness I am totally on board with! Bravo to the bride!"
And a third person commented: "HAHA, this is so petty and I’m living for it."
So, if there are any weddings in the diary in the coming months, make sure to swot up on what not to do.
