On Monday night Kate Middleton rubbed shoulders with Hollywood stars at the UK premiere of the new James Bond movie, Spectre. But this afternoon it was business as usual for the Duchess of Cambridge as she returned to her royal duties by carrying out the first of two planned solo engagements in London.

The 33-year-old fashionista headed to Islington Town Hall to spend time with staff and children from Chance UK's early intervention child mentoring programme where she learned more about the charities' work. Upon her arrival she was met by scores of well-wishers and greeted by Mayor of Islington Richard Greening before being led inside the Town Hall.

Chance UK offers art as therapy to children experiencing emotional and behavioural difficulties. During her visit Kate got to meet some of the children who have benefited from the scheme and was seen listening intently to some of their stories.

For the engagement, Prince William's wife chose a grey Orla Kiely dress and styled her brunette locks in a high ponytail. She showed no sign of fatigue from the night before when she gave the Bond girls a run for their money in a bespoke diaphanous pale blue full-length gown by her go-to evening wear designer, Jenny Packham. The sheer back revealed that she had gone bra-less for the occasion

Ahead of her visit, the mother-of-two, who is a royal patron of Place2Be, recorded a video message stressing her dedication to helping young lives. "Through Place2Be I have seen the benefits of offering children support for their mental health in the safety of the school environment. Both William and I sincerely believe that early action can prevent problems in childhood from turning into larger ones later in life."

On Tuesday evening the Duchess is expected to attend the 100 Women in Hedge Funds London Annual Gala in aid of the Art Room charity. The former art history student is also a patron of the 100 Women in Hedge Funds' Philanthropic Initiatives.
