Hi, I wonder if anyone here can help me to answer this question...
I got a preowned prada saffiano. I am not sure that:
1) did prada ever make the double zip in purple? (I saw this color somewhere, it seems a past season color)
2) why the bottom of my bag look so different from the other bags? The bottom of my bag is very narrow, and the stud is not round shape.
3) Is this BN1786?
Is it because this is a old version or I got a fake bag?

Thank you very much for the help!
