It's traditionally seen as a major wedding no-no.
But Duchess Kate threw caution to the wind for the Royal Wedding... seemingly wearing an all-white outfit.
Awks.

The mother-of-three - she only gave birth to Prince Louis a few weeks ago - arrived at Windsor with her elder children Prince George, aged four, and Princess Charlotte, three.
Both children are part of the wedding party for Meghan and Harry's Big Day.

We've looked at the footage and there is no doubt that her dress, jacket, and hat appear absolutely white.
Apparently, however, it is in fact YELLOW - with the sunshine giving it its distinctly white hue.

According to Rebecca English, the Daily Mail's royal correspondent, the Duchess of Cambridge "wore a primrose yellow wool silk tailored coat by Alexander McQueen.
"The Duchess of Cambridge is wearing a hat designed by Philip Treacy and shoes by Jimmy Choo."

We're still waiting for a decent, proper look at the outfit before making a final call on whether her attire is indeed white... or more of a pale yellow.
