yer best bet to find one would be @ a consignment shop or maybe ebay...but if it becomes an 'it' item again...forget about it...everything old is new again...
I had one too! Too bad I threw it away a long time ago.
OP, you can try looking for it in secondhand stores if you want the orignal ones. Or just wait a few more weeks and I'm sure there will be some popping up - both authentic & fakes. I'm not sure how you can have it authenticated though. Do we have some Dior experts here?
I have the J'Adore Dior tee!!
I bought it from ebay years and years ago, when SATC was still on.
I would say that is your best bet. I'm sure they will start popping back up now so check there and good luck!
