The Duchess of Edinburgh returned to her royal duties on Tuesday following the Christmas break.
Sophie, who turns 59 on Saturday 20 January, visited the Katherine Low Settlement (KLS), where she celebrated a milestone anniversary for the charity.
The Duchess looked elegant for her engagement, wearing a cream roll neck jumper and a Gabriela Hearst knitted midi skirt.
She added a pop of colour in the form of an emerald-green belted coat and her tan Gianvito Rossi knee-high boots, accessorising with one of her Sophie Hasburg clutch bags.
KLS is a charity based in Battersea, London, which supports over 500 vulnerable local people every week including the elderly, children, young people, their families and refugees.
It has long links with the royal family and was first opened by the Queen Mother, as Duchess of York, in 1924 and this year it celebrates its centenary.

She also joined a 'Love to Learn' mentoring session for children, delighting one little boy as she read him a story.

Sarah Gibb, Chief Executive of KLS says: "It was an absolute honour for us to welcome Her Royal Highness The Duchess of Edinburgh to Katherine Low Settlement in Battersea today. This year marks the charity’s 100th anniversary of bringing the Battersea community together and we are thrilled to start our centenary year with a Royal visit.
"KLS has been lucky enough to have had four previous Royal visits, since it was founded in 1924, and we are extremely grateful for each and everyone of these visits."
