An overcoat is necessary in the autumn, winter and spring.
Comfortable, low-heeled shoes are important, not only for the countryside, but also for sightseeing along cobblestone streets.
Swedes like fashion. However, they avoid standing out in glitzy attire and will never abandon their jeans for too long.
Informality is appropriate in most venues.
For business, a jacket and tie are generally expected for gentlemen. Trousers are acceptable for women on any occasion, including business.
