Stepping out for the King's Trust carol concert, Dame Helen Mirren gave a masterclass in festive style. Wrapped up against the cold winter weather in a timeless, deep green velvet coat, the star looked elegantly cosy, dealing with cool climes like a style pro.
A festive update on one of the best winter coat trends 2025, the actress's tailored outerwear felt quietly opulent with its jewelled tones and sumptuous, soft fabric, making it an elegant alternative to the classic long black coat that often comes out for party season.
Underneath her timeless outerwear, Dame Helen opted for a more contemporary outfit. She teamed a bold, bright green dress with a chunky silver hammered cuff and black suede boots with a pointed toe, which together created an eye-catching Christmas outfit, ideal for the festive occasion.
