Nice tie, Posh, but where did you leave your shirt?

She is one of Britain's most influential clothes horses, but Victoria Beckham's latest ensemble may not prove a runaway success on the High Street.

The former Spice Girl arrived for the launch of her new A/W dVb 08 denim collection wearing a satin-fitted, collarless tuxedo jacket with a matching waistcoat and a black tie... but no shirt.

She paraded the bizarre look in front of bemused onlookers at Jades boutique in Dusseldorf, Germany.

Victoria is currently on a European sojourn from Los Angeles, where she's based with husband David and their three sons.

Her visit coincides with the news that the son of her housekeepers has been arrested on suspicion of theft of items from their Hertfordshire home that were later offered for sale on eBay.

Gareth Emmett, 25, was held just 24 hours after his parents Eric and June had been bailed by police.

It is alleged the items, including football boots emblazoned with the names of the couple's three sons and designer outfits owned by former Spice Girl Victoria, were taken and later put up for auction on the internet site.

Beckham memorabilia has fetched hundreds of thousands of pounds at legitimate auctions in the past.
