Duchess Kate keeps warm in a custom blue Jenny Packham coat

By Laura Sutcliffe

Duchess Kate braved the cold on Tuesday as she stepped out at her new patronage, the Royal College of Obstetricians and Gynaecologists (RCOG). The Duchess of Cambridge, who is supporting the Nursing Now campaign, looked beautiful in a blue military-style coat with white trim, a custom creation by Jenny Packham. Kate let the topper hang open over her perfectly coordinated blue dress, anchoring the look with a pair of blue Jimmy Choo heels. The stunning wife of Prince William completed her ensemble with a blue clutch bag.

On the beauty front, she wore her long brunette tresses in waves and topped it all off with a dusting of natural makeup. There was no doubt about it – the Duchess looked positively radiant and sported a healthy pregnancy glow. Duchess Kate is due to give birth to her third child in April, ahead of her brother-in-law's wedding to Meghan Markle, which takes place on May 19 at St. George's Chapel at Windsor Castle.

The new patronages have been announced ahead of Her Royal Highness' visit to the RCOG later today, followed by a visit to St. Thomas'' Hospital where The Duchess will officially launch the Nursing Now campaign. The visits will see The Duchess learning about and supporting women's healthcare and global health work, and championing the professionals who work on the front-line.

The wife of Prince William has had an incredibly busy February so far. Last week, the mother of Prince George, four, and Princess Charlotte, two attended a fashion event with Sophie, The Countess of Wessex at Buckingham Palace on behalf of the Queen. The event was called the Commonwealth Fashion Exchange – which is an initiative which uses fashion as a common language and platform to help people understand the modern Commonwealth in a different way. The Duchess wowed waiting photographers in a beautiful dress by Erdem which hugged her pregnancy curves and skimmed her growing baby bump. Sophie, 53, also looked stunning in a black and red Burberry V-neck dress, which hugged her slim frame and totally optimised her super-polished and classic look.
