Hi guys! I am fairly new to prada(i am pretty much a louie/gucci girl). I purchased a green frame satchel from ebay about 3 months ago and just purchased the fairy bag. I have some questions......I noticed a lot of bags are referred to as cervo.....what does that mean/refer to??? Also, my fairy bag has a double zipper which I have seen on some of their other bags. Is this just for extra support? Just curious.....thanks for the info....
