Traditional overalls for all students in Finland. You wear them to the club/party events and at every outing, they have patches that are relevant (Recent Caribbean night had a patch with captain Jack Sparrow on it). You then sew them on to your overalls and wear them like badges collecting as many as you can. This makes for a very interesting way to get out and meet people and most importantly, an absolutely awesome souvenir. (don’t mind the messy room:) )
