A small, black handbag completed the look.
Prince Charles’ wife wore her blonde hair down around her shoulders.
She was not alone in her choice of outwear, however, with the rest of the Royal Family looking equally as winter-ready in a selection of classic coats.
Prince Charles opted for a simple, black coat atop his smart suit.
Similarly, his son Prince William wore a sophisticated black jacket.
The Earl and Countess of Wessex, meanwhile, opted for timeless mac style coats in varying shades of grey.
The married couple both donned scarves and globes to beat the winter chill.
In this latest appearance, the Royal Family came together to pay tribute to key workers across the UK.
They gathered to watch a performance of Christmas carols performed by The Salvation Army Band before greeting a number of local volunteers and key workers from organisations and charities in Berkshire.
