The Princesses wrapped up warm for the Together at Christmas community carol service in London.
The princess paired the ensemble with a small but chic black clutch.
In keeping with typical royal women protocol, she wore a pair of opaque black tights.
To top off the stylish outside she wore heeled leather black boots.
Her sister Beatrice looked equally festive, walking hand in hand with husband Edoardo Mapelli Mozzi.
She dazzled in a luxurious camel coat, fastened with two brown buttons.
It perfectly complemented her hair.
Like her younger sister, Beatrice also opted to wear Christmas colours, but rather than emerald green, chose a red headband.
To match this she carried a red handbag.
Both appeared to be wearing blush, and Eugenie went for a pretty pink lipstick.
Other royal women at the event were Kate Middleton, who actually hosted the carol concert.
She wowed, as ever, in a vibrant red dress with matching red suede pumps.
The carol service paid tribute to the individuals and organisations across the UK who supported their communities through the pandemic.
Ellie Goulding and Leona Lewis dazzled as two of the celebrity performers at the concert.
