The Duchess of Cambridge's top maternity style moments

It is estimated that over two billion people from across the globe tuned in to watch the Duchess of Cambridge wed Prince William in a Sarah Burton gown that wouldn’t look out of place in a fairy tale.

And the nation hasn’t been able to stop cooing over Kate Middleton‘s wardrobe ever since.

Dubbed ‘The Kate Effect’, the Duchess of Cambridge’s sartorial taste reportedly contributes a cool £1 billion to the economy. Though it’s hardly surprising, as every single item the royal dons has a shelf life of a mere few hours.

And with a third royal baby on the way, how will her new wardrobe affect the nation’s spending habits?

We revisit Kate Middleton’s best maternity style moments from her recently recycled Diane Von Furstenberg gown to her royal interpretation of one seriously coveted Topshop dress.
