I have made a list of places I would recommend anyone to visit when coming to Italy.
Depending on what you prefer (fashion, entertainment, art, history, summer vacation, food, trendy) I have made a note, next to each city, where you can have any of the above.
Supposing you begin visiting Italy from the northern part, here is the listing of cities/town I prefer:
Milan (fashion, entertainment)
Turin (history, art)
Portofino, Rapallo (summer, trendy)
Lake Como, Lake Maggiore, Lake Garda (summer)
Genoa (history, summer)
Venice (history, art)
Parma, Modena, Ravenna, Ferrara (history, food)
Bologna (history, food, entertainment)
Florence (history, art, fashion)
Pisa, Lucca, San Gimignano, Arezzo (history, art)
Forte dei Marmi (summer, entertainment, trendy)
Chianti Region (food)
Perugia, Cortona, Gubbio, Siena , Spoleto (history, food, art)
Rome (history, art, food)
Naples, Caserta (history, art, food)
Capri, Ischia, Sorrento coast, Amalfi coast (summer, food, trendy)
Palermo, Syracuse, Agrigento, Trapani (history, art, food)

Obviously the food is excellent anywhere in Italy, and in any city you walk through history. This is a simple guideline, in order to give you an idea what you can find, depending where you go.
