I'm not an expert authenticator like Whateve, but am a pretty well versed Coach shopper, and have to chime in -- I agree with her assessment, also I see that your creed shows a Coach outlet 'target' stamp, which along with everything else is additional reassurance. As a fan of that particular style & color, in my opinion you got quite a nice deal on that bag
With that said - I personally have had at least two authentic Coach bags that had such smooth, finely grained leather & soft fuzzy insides that I also wasn't sure about it being leather. I had both authenticated here -- and also had my leather repair person check the leather for me. They checked using heat applied to a teeny tiny piece removed from the excess leather overage an inconspicuous inside seam, as vinyl will melt if heated. My bags checked out fine - they just had very finely grained, soft well kept leather!
Hope this helps!
