Kate Middleton Glows In The Perfect Blue Winter Coat

Blue is definitely the warmest colour!

On Wednesday, Feb. 18, Kate Middleton visited the Emma Bridgewater factory in Stoke-on-Trent, UK, to see production of the mug the factory launched to support East Anglia's Children's Hospices, of which she is patron.

For the special occasion, the 33-year-old mom, who's seven months pregnant, wore a lovely blue MaxMara coat that revealed her growing belly, and a matching floral Seraphine frock underneath.

The Duchess of Cambridge styled her wavy locks into a half updo, thus showing off her signature blue sapphire and diamond earrings.

For accessories, Duchess Catherine was obviously in a matching kind of mood, and sported a navy clutch and matching blue pumps.

After her visit to the factory, Prince George's mum visited the Cape Hill Children’s Centre, where she met with families who are faced with difficult circumstances, including domestic violence and major health problems.

Earlier this week, the Duchess appeared in a video that was aimed at ending the stigma around mental health.

"The stigma around mental health means that many children do not get the help that they so badly need," Middleton said in the video. "This needs to change."

We're happy to see the princess get involved in important issues such as these!
