Despite the tweet implying the theft had accounted for the entire Marc Jacobs spring/summer 2012 collection, industry insiders suggested that clothes from the set which were due to be shown on the catwalk were safe in New York. The £40,000 figure cited by the police appears to confirm that the robbery did not account for a whole designer collection - one recent Marc Jacobs skirt alone is on sale for over £7,000 at the fashion website Net-A-Porter.
It's unclear whether the thieves are aiming to sell or copy the designs. It would be difficult to sell the garments online without drawing attention to them - and only very tall and slim thieves would be able to wear the items which were destined for models on the pages of Vogue, Elle et al.
A spokesman from the label refused to verify any details of the theft. Emails to Ms Barthel and to staff at the firm's American public relations office also went unanswered.
A Metropolitan Police spokesman later confirmed: "We are investigating an allegation of theft which occurred in the Mount Street area at approximately 8am on Wednesday after a quantity of clothing, bags and shoes reported to be worth £40,000 were found to be missing."
With the label reluctant to divulge the facts, disinformation has quickly spread online as fashion bloggers and magazines tried to work out what had happened. Reports range from a lorry, in transit from Paris to London, being hijacked to samples being taken from a train.
