I have traveled to Europe every year for the last 10 years because like most of you I fell in love with the people and the different cultures. Over the years I have seen other tourists wear clothing that I though was somewhat "tacky", an example is the wide brim sun hat that tourist wear yet 2 years ago I went to Italy and my wife talked me into getting a Tilley hat and it was a life saver in the several days when we were out in the hot sun seeing the ruins.
I have always thought that "convertible" pants (the legs zip off) were the epitome of "I am a tourist" in clothing but again my wife talked me into trying a pair when we went to Greece last summer and they are great because most the time it was hot but there were a few days that it rained and was cool.
This May we are heading to Sicily for 2 weeks and I've decided to take only two pairs of convertible pants for the whole trip along with 5 shirts, since I'll be wearing one pair of pants along with a shirt I will only pack 1 pair of pants and 4 shirts. So, I guess the take home lesson here is that when I listen to my wife good things happen!!
