I think your trip was awesome!; I've been to the same cities you went to except Milan and Venice which I plan to visit on a different trip, instead I decided to go to Napoli and eat traditional Pizza and Pompeii and Erculiano, two cities preserved from the year 67 AD when Mount Vesuvio erupted its hot ashes over it in the middle of the night. I thought Napoli was a little ghetto but its bay and the castel dell'ovo and the street markets were very unique. I see that you did a lot of fashion shopping which I guess its a must for women of your age and clubbing. Each city in Italy has its treasures, but for me Saint Peter's Basilica in the Vatican was the most impressive man made structure that I have ever seen and walking all the way up the dome and when you come out and you can see a 360* of Rome is magnificent! also I recommend when in Rome going to see the Roman Baths, the Borghese museum and art gallery and of course the Sistine Chapel.
