Haalarinkastajaiset 24th of October from 5pm to 8pm in Bulevardi Campus (Engel P317-Auditorio)

Overalls, seems like everyone has them. They are corner stone of the student life when something is happening.

Haalarinkastajaiset are a traditional event during which you get trained in the ways of wearing overalls. Maybe you have seen someone who has sewn someone elses sleeve or leg of the overalls to his/hers overalls. How do you maintain your overalls? Are there any rules to wearing overalls?

HTO and UIO will give answers to all the things you could think about overalls and student culture.

The event doesn't cost you anything!

The info about afterparty will be disclosed during the event
