19th October 2015 Kate made her the very first appearance at the Palace state dinner in honor of Chinese president Xi Jinping.
It is noticeable that despite many speculations, Kate didn't wear the Royal family Order of Queen Elizabet II.
However, following the white tie dress code, Kate wore the bespoke Jenny Packham gown the same shade of red as the Chineese flag.
Also she wore the Papyrus tiara, matched them with chandelier earrings and two diamond bracelets. One of bracelets used to be a Queen Mother choker, another one is the wedding gift to the Queen Elizabeth II.
I wonder what were shoes! I guess they might be Jimmy Choo 'Vamp' sandals to match Kate's diamonds.
