After years of buying and selling Juicy, I recently received my first counterfeit off of ebay (a tracksuit which I promptly returned).  In order to help others discern the subtle differences that counterfeit items inevitably have, I'd like to share several tips to help you authenticate Juicy items. 

 First, examine the cut of the garments.  The FAKE Juicy fits very baggy and loose, which is NOT how real Juicy fits when you have the correct size. 

Second, REAL Juicy uses YKK zippers on their tracksuits (the "J" shaped ones).  The counterfeit I received did NOT have YKK zippers (although they were a "J" shape). 

I'll be updating this in the future.  Meanwhile, please check out the other guides on spotting counterfeit items before bidding!  Selling counterfeits is AGAINST ebay policy!
