Which one do you recommend?

I'm going to go ahead and disagree with pretty much everyone. My favorite small bag is a Ciao and beyond that I really like the Nuvola and Scuola. If you're graduating HS and going on to college one of the backpacks might be nice. It just depends on what your lifestyle is. I walk everywhere and wouldn't want to carry a Zucca.
 
Most girls on my campus or other colleges I know of, end up carrying everything in a tote or messenger- so if you want one to use in school, a BV or Campeggio would be suitable. If you just want a purse- zucca first- gioco second- More complete prints tend to show up on zuccas and on the gioco, if you carry small heavy items, the print on the bottom of the bag is what will be noticed most.
