She has made no secret of her desperate desire to be a style icon.

But Victoria Beckham's latest bizarre outfit only confirmed her status as fashion victim extraordinaire.

Wearing a raven black headpiece that almost defied description and puckering her face into the oh-so-familiar pout, Posh Spice appeared to have beamed down from another planet.

Robo-Spice: Victoria Beckham shows off an unfortunate Teletubbies-style haircut in the new ad campaign unveiled today for Marc Jacobs

Her usual sleek bob had been transformed with the help of a fringe made of feathers all topped off with a bow.

Posh was out shopping today with son Romeo and Desperate Housewives friend Eva Longoria

Le freak, c'est chic?: Fashion watchers may have believed the Guantanamo look was a new low for Posh (right). But the brilliant orange atrocity was at least redeemed by her hair

The ensemble was finished off with the ultra-expensive Mika handbag, a crocodile-skin confection festooned with gold chains and costing the best part of £1,000.

Whereas the hard-edged look may suit the likes of Kate Moss or supermodel du jour Agyness Deyn, Posh - once again - struggled to carry it off.

Victoria was pictured shopping with her friend, Desperate Housewives star Eva Longoria, today in what hopefully is the start of a wardrobe makeover. The pair hit up Dolce and Gabbana before heading home.

In the past, Victoria's endlessly rotating carousel of freakish outfits have drawn parallels with Cruella de Ville, Lady Penelope from The Thunderbirds and Sesame Street's Big Bird.

She hit a new low earlier in the year after turning up at New York fashion week in a brilliant orange extravaganza which resembled a Guantanamo Bay inmates' trademark jumpsuits.
