Martin Creed installation at Victoria Beckham's store

We always know that any party thrown by Victoria Beckham is going to be a seriously stylish affair.

And last night was no exception as she hosted a bash to celebrate the first anniversary of her store in Dover Street.

Knowing that she had to dress to impress, Victoria chose a suitably chic ensemble for the special occasion.

But given her recent run of style successes – think that printed coat from her SS16 collection and the 90s-inspired frock she wore at London Fashion Week – it was always pretty obvious she was going to nail it, right?

The 41-year-old opted for head-to-toe black, styling a camisole featuring spaghetti straps with impossibly skinny trousers.

VB, who arrived with handsome husband David, added a touch of sparkle to her outfit by draping a sophisticated sequinned jacket around her shoulders.

That’s totally a piece that we’ll be desperate to don over the Christmas party season.

She accessorised with a pair of towering pointed courts and pinned her long brunette hair up.

Naturally, the bash had a guest list made up some of the biggest names in the showbiz industry including Naomi Campbell, Arizona Muse and Christopher Bailey.

Looking super-sleek in a form-fitting LBD, Ellie Goulding also stopped by the gathering.

One thing we did notice, however, is that Victoria and the other attendees weren’t looking quite so picture-perfect when they emerged from the shop later on.

The fashion designer and her pals exited the venue with dirty marks on their clothing.

Wondering what could have possibly gone on inside?

Proving that she really has got connections in high place, Victoria had arranged for a special installation of artist Martin Creed’s work to be unveiled during the evening.

Translation: The guests got to fool around in a sea of giant white balloons. And judging by pictures and videos shared on Instagram it looked like A LOT of fun.
