In terms of what to wear for tours, the principle is to wear respectful dress and dress appropriate for the conditions.
IMPORTANT: Anyone with shoulders and/or knees uncovered risks not being allowed into certain holy sites. No refunds will be offered and we will only skip a given site if the whole group is refused entry. Other than that, just dress comfortably! But remember you are in Italy, so no pyjamas in public. Some of our tours are long and require a lot of walking. The ground in some of the ancient churches and archaeological sites we visit is not always even (and neither are the pavements in Rome). It is recommended to have a sturdy pair of shoes, boots or sneakers and check the weather forecast in case you need to bring an umbrella or jacket.
