Do men need a sports coat for any activity on this trip? Are long athletic shorts and t-shirts appropriate daytime attire for teenage boys (excepting the Vatican tour)?
My trip documents say: "Your itinerary includes accomodations in award-winning hotels and meals in many fine restaurants. You may enjoy dressing up a bit in these locations, however, it is certainly not required. Men do not need to wear a jacket at dinner. In Europe, it is customary to dress more formally for dinner than is typical in the United States, especially in the finer restaurants. Slacks or a dress for women and a jacket for men are acceptable dining attire. It is advisable to avoid wearing jeans, sneakers or shorts for dinner."
So, it seems like you can wear what you wish for signtseeing, including athletic shorts (except for the Vatican, as you mentioned) but for restaurants, maybe long pants would be better.
