Stella McCartney Switches On Her Store's Christmas Lights With All Her Celebrity Friends

Stella McCartney invited all her celebrity pals along to her Bruton Street boutique on Wednesday night as she hosted a glitzy party to turn on the Christmas lights in store.

The guest list was pretty fabulous too. Salma Hayek, Sienna Miller, Daisy Lowe, Mick Jagger and Judi Dench (in leather) were there to celebrate with the designer.

Salma looked immaculate in that kinda fresh-from-Hollywood glowing way in a lemon button down coat. It was crisp, collarless and teamed with a matching tote.

Yes, Salma is a total stunner but it was still all eyes on 42 year-old Stella who kept her look effortless and classic in a black mini dress with three-quarter length sleeves and silk peplum detailing.

Sienna Miller also showed support for her designer girl and arrived looking all casual and cool, just like she does every single time. The look was played down with a monochrome print top, grey skinny jeans, buckle strap ankle boots and a black duffle coat.

Oh to be moving in these stylish circles: the best of British design, A-list actresses and actual rock stars. Take a look to see who was getting their Christmas vibe on last night with Stella. Yes, that's Dame Edna you spy...
