This is why Kate Middleton wore green to the BAFTAs amid the Time’s Up all-black dress code...

At this year's Golden Globes, celebrities wore black as a show of support for the Time’s Up movement.

And today's BAFTAs followed suit.

So naturally, royal watchers were eager to see Kate Middleton's dress choice for the evening.

The Duchess of Cambridge hit the red carpet with her husband, Prince William, wearing a dark green cap-sleeved Jenny Packham gown.

She accessorised with emerald jewellery, suede Prada heels, a black clutch and a black sash underneath her bust, which accentuated her baby bump.

So why did the mum-of-two opt to not wear black?

Because it's against royal protocol.

The royal family are not allowed to be seen as making a political statement.

And fans are not happy about the Duchess' decision...

The sexual harassment group Time’s Up was formed in the wake of the Harvey Weinstein allegations back in October.
