If you don't already know, Kate Middleton is on somewhat of a winning streak when it comes to her maternity wear of choice right now.

Days after wearing an array of Catherine Walker coats, a beautiful yellow floral dress by British designer Erdem, and carrying a Chanel handbag, the pregnant royal proved she's the queen of royal fashion in an ornate, floral-printed blue velvet dress for her last night in Sweden.

The 36-year-old attended a reception to celebrate Swedish culture at the Fotografiska Gallery in Stockholm wearing her second Erdem dress (a similar version is available here) for the final night of her Scandinavian royal tour with husband Prince William.

Meanwhile, Prince William matched Kate's blue look with an electric-blue suit of his own.

During Prince William's speech at the event, he spoke of how he and Kate have enjoyed their time in Sweden, days after enjoying a game of bandy hockey and visiting Sweden's national centre for architecture.

'It has been a great pleasure to be in Stockholm these last two days,' he said.

'Sweden is a country that holds a very special place in the heart of my family, and for all British people. And it has been a joy to see that our very high expectations for this beautiful city have been fully met.'

At the end of his speech, William thanked the Swedish couple for their hospitality, and suggested the pair visit the UK with their children, Princess Estelle and Prince Oscar, so they can finally meet their growing brood.
