Posh shows Claudia and Dita how to behave at a fashion show

With Schiffer and Von Teese wearing similar oversized sunglasses as they sat inside the venue for designer Mouret's Spring/Summer 08 show, it appears that both Posh's pose and style are sweeping the world of celebrity.

Strike a pose: Victoria Beckham's stilted style of posing appears to be catching on, as it's adopted by model Claudia Schiffer (centre), and burlesque star Dita Von Teese, seen today at designer Roland Mouret's Paris Fashion Week show

Lookalike: Dita wears the Mouret 'Moon' dress but Posh trumps her with a dress from Mouret's 08 Spring/Summer collection

And if further evidence were needed, Dita, who was recently signed as the face of Wonderbra, wore Mouret's sell-out 'Moon' dress.

The same dress famously worn by Victoria when husband David was unveiled as a new signing for US football club Los Angeles Galaxy.

But at least Dita opted for a less headline-grabbing midnight blue shade, as opposed to the hot pink colour worn by Mrs Beckham.

Apparently Mouret fan Victoria was so determined to be the first to be seen in a 'Moon', she bought the entire collection off the runway and wore her dress a full five months before it went on sale.

But style stands still for no woman, as it appears Victoria has triumphed again in the first-past-the-post style stakes.

The Spice Girl, who has earned a cool £10million from the London dates of her reunion tour alone, posed smugly next to Dita in her last season 'Moon' frock, while wearing a lightweight grey fitted shift-dress from the new RM collection.

While Schiffer wore a similarly styled black skirt.

Victoria, Claudia and Dita were among the front row guests when designer Mouret unveiled his spring/summer 08 collection.

Mouret is the creator of the red carpet sensations, the Galaxy and the Titanium, and, more recently, the hourglass-shaped 'Moon' dresses as worn by celebrities such as Cameron Diaz, Madonna and Carol Vorderman.

He is now under the wing of Simon Fuller, the TV and record producer, manager of the newly reformed Spice Girls and not a known fashion-lover.

And unsurprisingly, Mouret has Victoria to thank for the now successful association.

As the introductions were brokered by the fashionista and Fuller's girlfriend, both fans of Frenchman Mouret.
