Fake Marc jacobs Victoria beckham cancer t-shirt?

[Shazza]

Hi, is there anyone who has actually been out & purchased one of the Marc Jacobs ( victoria Beckham ) t-shirts from a reputable source? I have seen so many different variations for sale on Ebay that i am confused!!! All of them claiming to be original with receipts...some are brand new with tags ...of which i have seen two different type of tags...some have wash labels inside some dont.....some state very clearly that they dont come with tags from Marc Jacobs Flagship Stores??? I have even seen some that have not got Victoria Beckhams name on the back of the t-shirt on the Thank You list!!! I myself have purchased 2 from Ebay USA...and i am not at all convinced of their authenticity....No wash /care label inside no seams down either sides...plastic loop holding the tag on. Yet they came wrapped in Marc Jacobs Tissue paper & the seller sent them insured ( Had to pay further charges for Customs ). Did she do that to be more convincing of authenticity? I havent as yet left Feedback.
