Pregnant Kate, the Duchess of Cambridge chooses a very special outfit to dress her baby bump for royal event

Pregnant Kate, the Duchess of Cambridge has chosen a very significant outfit for her latest royal appearance.

Kate attended a special gala dinner held at Kensington Palace last night for the Anna Freud National Centre for Children and Families, a children’s mental health charity, of which Kate is a patron.

The Duchess chose a very special outfit for the black-tie occasion, which subtly showed off her neat baby bump.

Picking an old favourite dress from her closet that she loved wearing when she was pregnant with Princess Charlotte, Kate looked radiant in the black lace floor-length Diane von Furstenberg gown.

The Duchess was first spotted in the dress in 2014, a few months after she had revealed she was pregnant with her second child. Kate loved the dress so much, she then wore it to a friend’s wedding in London a month later when she was around four months pregnant with Princess Charlotte.

As the Duke and Duchess of Cambridge have revealed that Kate is due next April, we now know that Kate is currently around four months pregnant with her third child, meaning that the designer gown would have been an obvious choice for Kate for the evening.

Seemingly her go-to second trimester dress, the outfit was perfect for the glamorous Gala Dinner that the Duchess attended at the Orangery at her home Kensington Palace last night.

Over the course of the evening, Kate met with people who are involved with the Anna Freud Centre, as well spending time with some of the families who benefit from the charity and its vital work.

The gala dinner drawing attention to child mental health issues and the important working being done in this field follows a surprise round-table discussion, hosted by the Duchess at Kensington Palace on maternal mental health.

Royal insiders believe that Kate’s desire to step-up and host official engagements by herself on subjects that are important to her is a sign that she is ready to ‘carve out a more serious role for herself’ within the monarchy.

The Duchess of Cambridge’s presence at the special event marks Kate’s second private solo engagement at the Palace since announcing her pregnancy in September.
