Might be best if she doesn't let Meghan see that sign, or there could be trouble... Press Association have released some infographics comparing tomorrow's royal wedding to ones gone by.
Etiquette expert Myka Meier, who has trained in London under a former member of the royal household revealed that women should choose a dress that covers their shoulders, with a hemline no shorter than their longest finger, when their arms are at their side and no longer than mid-calf.
This royal super-fan was keen to show where his allegiances lie as he turned up dressed in a suit and covered in Union Jacks, as well as wearing a hat and sunglasses with the flags emblazoned on them.
WATCH: Throughout history, some of Britain's royals have challenged convention, especially when it comes to romance.
