Sure, Italians break out the va-va-voom when it’s time to hit the club. In daily life, however, most tend to cover up and you should, too. Modest clothing covering shoulders, knees, and midriff is required to enter most major churches (think St. Peter’s Basilica in Rome), and you don’t want to look like those poor chumps who have to tie a disposable plastic poncho around themselves to visit the Sistine Chapel.
In addition to getting you into churches, more coverage will protect you from the unforgiving Mediterranean sun. Opt for light linen and cotton short-sleeve tops, pants, and long skirts; alternatively, throw on a pair of knee-length shorts and bring a light wrap with you to cover your shoulders.
