She was almost  upstaged by colourful artist Grayson Perry during a visit to a London school  yesterday, but this morning, all eyes were back on the Duchess of Cambridge as  she met foster carers in Islington.

The 33-year-old  opted for a more fashionable look than yesterday’s pared-back smock dress by  maternity label Madderson, teaming her brown silk Hobbs dress, which is not part  of a maternity line, with opaque black tights and court shoes.

High street brand  Hobbs is one of the Duchess’ favourite labels and a frequent choice for  engagements. In November, she was seen in a polka dot top by the same label  during a reception she hosted at Kensington Palace.

(Working mother: The Duchess, who is six months pregnant, was undertaking her  second engagement in as many days)

(Thrifty choice: The Duchess of Cambridge arrived at the event in London’s  Islington wearing a Hobbs dress that is currently reduced to £50)
