prada style verification

  1. hey i'm thinking about buying a school bag for my sister as a graduation present. i wanted to buy her the single clasp prada messenger.

    i found this on bluefly, but the size of this bag (12 x 9) is smaller than the one (14 x 11) that i was looking at in the actual store.

    do any of you prada experts know if prada make a smaller version of their single slip nylon messenger? i guess i'm just wary of bluefly.

    any help will be much appreciated. thank you!
