Showing her support for the Scott-Amundsen Centenary Race to the South Pole expedition, Kate Middleton was back on style form in a Rebecca Taylor suit.
As elegant as ever, Kate was back in her favourite royal hue, and even matched that Anya Hindmarch Marano clutch we've seen her wear before, with suede Episode pumps for an all-blue ensemble.
With Prince William by her side, Kate cooed over the baby son of one of the adventurers - describing him as "very cute".
The Royal couple were at the reception to celebrate the expedition which recreated the famous South Pole race between iconic explorers Scott and Amundsen - 100 years on.
Later on the pair are to attend a WW1 centenary event.
