Kate wears a white jumper, high-waisted flared trousers and a long white coat. The princess is shod in light suede pumps with heels. And he holds a miniature white bag in his hands.

The princess has beautiful styling in waves, evening eye makeup and accentuated cheekbones with blush, and lipstick on her lips is brighter than usual. The beautiful look is complemented by dangle earrings from Van Cleef & Arpels and an engagement ring on her finger.

Katherine arrived earlier than the rest of the family, as she is meeting key people ahead of today's service, including musicians, who will be playing and performing songs at the concert tonight.

Last night, Kate released a teaser for Royal Carols: Together At Christmas, which was broadcast on ITV.

"Join me on Christmas Eve for a special Christmas service as we extend heartfelt gratitude to all those who support the youngest members of our society in these crucial early years."

This year's concert is dedicated to children and early childhood development, a topic that the Princess of Wales cares about so much.
