The students I met with reported feeling very safe in Helsinki. I experienced the same. It was dark much of the time I was there, and I never felt uncomfortable walking around by myself. The students joked that a drunk person on the street is more likely to sing to you than harass you. The drinking/singing combination is evidenced by the popularity of karaoke as well as sitz parties. Sitz parties sometimes include a seated meal but always include singing—and often even songbooks! Then there are the coveralls...

Each school in Finland is assigned a color for coveralls. Students wear them to parties and decorate their coveralls with the patches they get from different events (a bit like a girl scout sash). I have to admit, I don't think it's the best look, but the students are super enthusiastic about this tradition.
