Duchess Catherine looked festive in red for the Anna Freud Centre's children's Christmas party on Tuesday (15.12.15).
The 33-year-old royal showed off her slimline post-baby figure as she recycled a red Alexander McQueen dress that she has also worn on two previous occasions.
She teamed the dress, which features a pleated skirt, with a pair of low black heels.
Catherine's hair, which was recently cut to take it from long to a trendy shoulder length cut, was stylishly blow dried.
As ever, the royal appeared to have done her own make-up, going for her favourite look of dark eyeliner and a pale lip.
Catherine was seen meeting staff outside the London centre before heading in to join in the festivities.
Following a tour of the centre, Catherine will watch a performance by parents, children and staff at the centre, including a section which allows the children to show the skills they have acquired through drumming workshops.
The visit has allowed the duchess to see how the children are getting on since she visited the school at the start of this academic year in September.
Catherine, who was known as Kate Middleton before she married William in 2011, decided to make the Anna Freud Centre her first official royal duty following her maternity leave after the birth of baby Charlotte three months ago.
The school offers an alternative way of teaching by allowing parents to sit in on lessons and attend their own classes as a way of learning how to effectively support their children.
