Capri, off the coast of Sorrento in southern Italy, is a great day-trip destination. There are plenty of historical things to see, as well as numerous shops, including big names like Zegna, Fendi, Prada, etc.
Make sure you head to the top of the island via the chairlift! Although this is a little bit scary, the views once you reach the top are unmatched and worth all the fear you experience during the chair-lift section. Know that the shops tend to close around lunchtime, so plan accordingly. After enjoying your meal, instead of heading directly to the shops, take a stroll around the island. There are plenty of beautiful villas and breathtaking views to occupy you while the Gucci shopkeeper is taking a break!
Other fun notes: Look out for famous people! Numerous famous people have homes on the island, so keep your eyes peeled! Also, Capri is a favorite location for shooting movies! Watch for this as well.
