I was going to recommend eBags Exo spinners shipped to wherever you're staying, but shipping to Italy looks ridiculous. I bought these a few years ago with the intent of upgrading to a "name brand" if/once they fell apart. Turns out they're fantastic, and ~$170 for larger bags.

Going and seeing what Rinascente has is a good recommendation. You might find something you like by looking versus seeking out a specific brand's store.
