Princess Kate steps out in green at the British Academy Film Awards

Almost every celebrity on the red carpet donned black as a nod to Time's Up.

The dress code is similar to other red carpets, most notably the Golden Globes, when women and men both showed their support for gender equality and human rights for women.

Others said that it was a missed opportunity for Kate, and argued that wearing black was not a political statement but rather simply an affirmation of women’s rights.

Kate accessorized her gown with stunning emerald and diamond earrings, which she donned previously in New York when she and Prince William attended the 600th anniversary benefit at the Metropolitan Museum of Art of their Alma mater St Andrews University.

Princess Kate accompanied William, who is president of BAFTA, and also wore a glittering matching emerald and diamond necklace to the Awards ceremony.

"Catherine and I are extremely pleased to be here amongst you all this evening," William said at tonight's event. "The Film Awards are just one part of BAFTA's activity. I have been privileged over the years to experience first-hand the impact of its work in the United Kingdom, in Los Angeles, New York and Asia -- work ranging from scholarships and supporting new talent, through to masterclasses with the very best in the film industry -- many of whom are here this evening."

"Your support of BAFTA -- sharing skills, expertise and time -- means we can ensure the growth of creative talent in the UK and internationally. It ensures that we can do much, much more to help talented people from all backgrounds to be given the opportunity to succeed," he added.

"As we approach the BAFTAs, our industry's time for celebration and acknowledgement, we hope we can celebrate this tremendous moment of solidarity and unity across borders by coming together and making this movement international," the letter states.
