Swiss Dress Code
As with the Germans, the Swiss dress smartly for business but do not restrict themselves to the dark blue and dark grey suits favoured by many U.K. and Asian business people.
It is common for men to wear sports jackets and trousers with a shirt and tie in business situations and for women to wear smart casual clothes. Trousers for women are commonplace.
Some of the more conservative elements of the banking sector still prefer the more formal attire of suits and ties and if visiting such a firm it is probably better to err on the side of caution.
The climate is very variable, so ensure you are dressed appropriately for the season.
