It's a total counterfeit. verify at http://ihatecounterfeitbags.info/stripebags. It's a very common type of counterfeit! Counterfeits are illegal. Not sure if you fall into that category, since no money is exchanging hands... but thought you should know!
There really isn't any difference between a counterfeit purse and a counterfeit $20 bill. Literally every bag with that bow that pretends to be a Kate Spade purse is counterfeit. It's the most common counterfeit around, and oddly enough, it's not a design that kate spade ever made!
