From welcoming Princess Charlotte into the world to attending her first state banquet at Buckingham Palace, it has been a whirlwind year for the Duchess of Cambridge.
Whatever the occasion, Kate stunned with her fashion choices and – most importantly – wasn’t afraid of having a good laugh along the way. Here are some of the Duchess’s 2015 highlights.
Kate was left “moved” after meeting foster carers at the Fostering Network in Islington, north London.
And later that month, when six months pregnant, the Duchess told teenagers she could feel her baby kicking.
Kate showed off her artistic skills by helping to paint a mural while visiting the new Ben Ainslie Racing sailing centre.
And despite wearing a gorgeous, patterned Seraphine dress and blue coat, she got stuck in during a pottery class.
Her baby bump was covered by a gorgeous pale pink Alexander McQueen coat at the Commonwealth Observance ceremony…
And by this stand-out dalmatian Hobbs coat as she visited an art exhibition.
She enjoyed a tour of the set of Downton Abbey, and met with cast and crew.
And was joined by William and the rest of the Royal Family at St Paul’s Cathedral to honour the sacrifices of Britain’s armed forces in Afghanistan.
At an annual St Patrick’s Day parade, a heavily-pregnant Kate told one mother she was struggling to get back up when she bent down.
But she still looked radiant in a fuchsia pink Mulberry coat as she visited the Stephen Lawrence Centre – her last public engagement before giving birth.
Kate welcomed Princess Charlotte into the world – and looked flawless despite giving birth just hours before.

The royal couple watched Andy Murray storm to the Wimbledon semi-finals on Centre Court.
But Kate dressed down for the America’s Cup World Series – and entertained a young guest when high winds meant the day’s sailing was cancelled.
Kate smiled as she was presented with gifts made by inmates during her first visit to a prison.
