For starters, don't underdress for church. Bare legs and bare arms are not appreciated, especially during services when the church is occupied. Some monasteries will provide coverups for unprepared tourists to wear inside. But if you have to see inside that charming chapel and you have nothing to cover up with, usually an apologetic shrug and gesture at your bare arms and/or legs to whatever black-garbed yia-yia is in attendance will gain you a smile and a forgiving welcome anyway.
