Ok- Shouldn't we consider whom is paying for these shopping items? I love Paris, but as a teenager, I doubt that she would be able to find a lot of fashion that is in her price range that isn't at a department store or a market. Same with Florence and Rome. Great goods but you run into some high prices. I think that the OP needs to tell us what her daughter is looking for and maybe some sort of a price range/budget that her daughter has to spend once they get there. Also, is the OP going with the daughter? If not, I wouldn't go to a lot of these places as a grad trip without a parent.

Just my 4 cents.
