On a night where all anyone can talk about is the Time's Up movement – and wearing black to show support of it – only a very brave woman would dare set foot on the BAFTAs red carpet wearing another colour.
As it turns out, however, our future Queen is one such lady...
Accompanying her husband Prince William, who has been a president of BAFTA since 2010, the Duchess of Cambridge joined Hollywood’s finest on the red carpet tonight wearing a dark green Jenny Packham gown.
If you're thinking 'UMMM WHAT NOW?' we don't blame you. However, two royal reasons most likely lie behind Kate's decision to eschew the unofficial dress code.
The first is that, as a member of the royal family, lending her obvious support to the Time’s Up movement by dressing all in black might have been interpreted as a breach of protocol, as the royal family are supposed to remain politically neutral.
Not only that, but royal etiquette dictates royals should only wear black when attending funerals or Remembrance Sunday.
For all the other of this year’s attendees (many of whom have lent their names to an open letter demanding an end to sexual harassment worldwide), the decision to dress in black was a lot simpler.

Was she right or wrong not to go all in black? Well, it's likely she had no choice. And if that was the case, the green gown with the black band was a smart way of negotiating her way through this sartorial hot potato.
