Prince William and Kate Middleton celebrate their sixth wedding anniversary on Saturday 29 April 2017. Millions of people around the world watched as Kate walked down the aisle at Westminster Abbey in a bridal dress designed by Sarah Burton at Alexander McQueen. The photo of the newlyweds kissing on the balcony at Buckingham Palace made front pages all over the world.

After the wedding, Kate – oldest daughter of party planners Michael and Carole Middleton – became Her Royal Highness The Duchess of Cambridge. She has since become a fashion icon, with fans all over the world keeping a watch on what she wears, giving rise to the term, ''Kate effect''. She has constantly been in the public eye, carrying out various engagements. The royals have had two children: Prince George (born on 22 July 2013) and Princess Charlotte (born on 2 May 2015).

As Prince William and Kate Middleton celebrate their anniversary, IBTimes UK looks back at their first six years of marriage.
