Princess Kate has been seen wearing the Order of King Charles for the first time - and it's said to show the 'true feelings' the royal has for her father-in-law.

For her state banquet gown, Kate chose a dark red Givenchy evening gown designed by Sarah Burton, who also designed the princess's wedding dress. Kate and William shared their looks ahead of the state banquet on social media, captioning a photo, "Ready for what promises to be a wonderful State Banquet this evening in Windsor."

The Princess of Wales has worn the Queen Mary Lovers’ Knot tiara for 10 of her 15 tiara moments in the past 14 years.
