Hello, I just bought this bag from Ebay believing 100% it was authentic. Sent the auction link to my friend (an old time Prada lover) and she has just pointed out that it's actually a very good replica. What do you think? http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260550724305 Apparently all the signs are there, but according to my friend there are inconsistencies (she didn't specify, but is adamant i shouldn't pay for it). I'm broken hearted. Please advise? If it's a fake I won't even send the money and will report the seller.
