I dress usually very informally at home and when I go out, so that means I rarely wear a tie or jacket.
At the same time I don't want to stick out like a sore thumb, but after looking at Rick Steves's suggested packing list, I am wondering whether I can forgo the long-sleeve (3-4) and short-sleeve (1-2) shirts and "get away" with simple but comfortable quality knit shirts and T-shirts, with a super light North Face thermoball jacket and 2-3 pullovers plus a windbreaker/rain jacket.
I know the Italians pay much more attention to attire and style than Americans do, generally speaking, so I also do not want to cause consternation on that end, either, as in a restaurant-cafe or museum or just on the street.
So at the same time I do not want to create the impression of being a slob! Just neat and simple. In other words, I don't dress for fashion at all.
Any advice or info from those who have been on a RS Italy tour?
