Well I can't say I am any expert - but I do have developed a vast knowledge after years of following years of Juicy Couture... I hope the info I provide here is somewhat useful to someone
This was one of the earliest styles of Juicy Couture Leather bag, I have seen this stye in person in black smooth leather when it first came out, as well as a baby blue smooth leather one on sale at Century 21 when I went on a trip to NYC last year (the black made the bag look really really mature, which wasn't really fitting with the image they were typing to maintain for the brand, so they weren't really that popular) - retail was around the mid to high $300 range - the other one is a big shoulder shopper tote that looks somewhat like a Hermes Birkin (only somewhat).
I have seen this type of leather, again really long time ago (but in a baby blue) on other small Juicy Accessories - like a cylinder makeup clutch.
So putting the 2 and 2 together - it is possible that JC has made this bag in this type of leather. Too bad it is only 1 picture - she should check the tag inside, and the lining - but considering what you told me about your friend Lexie, I don't think she would really care...
So far, to my knowledge, I would worry about getting fake Juicys if I am looking for a (note that the styles are the most popular styles):
- Daydreamer
- velour bowler, anything velour, for that matter - such as wallets, pet carriers, etc
- baby fluffy, both in the leather or the velour ones are extensively counterfieted
- many of the leather bags that was released last year with the lavender lining (Bridget or Jen, the Lady D, and the P & G satchel)
