Hello,
You would be most likely to see a Swiss carpenter today wearing a baseball cap a t-shirt and some of those big ol' shorts. I have noticed that for some reason, who knows maybe with connections right back to old fashioned guild practices, that all through Western Europe every trade or even manual profession, for example farmers, seem to have their own standardized dress elements. Here in Holland the farmer - men and women - wears a light blue cover-all. And the dairy farmer has a funny green hat. Of course these days it's not strictly adhered to, but in more formal situations, these old group identifications are clear. Last week I attended a wood auction and everyone there seemed to be wearing dark green which was always the uniform of the woodsman's professions. Here's a picture of some fine young rural Swiss carpenters I plucked from the
internet
Greetings,
Don Wagstaff
