But several hours later, as her flight touched down in Ottawa to kick off her tour of Canada with husband Prince William, Kate had changed into a stunning scoop-backed lace shift dress.
The new Duchess of Cambride accessorised her blue and cream frock by Canadian designer Erdem Moralioglu with a pair of nude patent LK Bennett heels and matching box clutch.
Kate had also changed her hairstyle mid-air, sweeping it back off her face into a chic half up-do.
The arrival of Kate and Wills, both 29, has caused hysteria in the country, with thousands of fans gathering to get a glimpse of the newlyweds.
'Bonjour #Canada! The Duke and Duchess of Cambridge have arrived #royaltour2011,' Clarence House Tweeted yesterday.
'The couple will first recognise the huge contribution made by Canadian Armed Forces at the National War Memorial in Ottawa #royaltour2011.'
