All the graduates wear caps that look like marine/sailor hats? Heres a picture.
Along with this, the guys all wear something that looks like a white sailors uniform. I don't think caps and gowns (like in the US) are a thing here.
Whats really fun about what they do here is that groups of friends rent out these army bus/ garbage truck looking things and they party in them all weekend. The weekend after they graduate is spent in these trucks in their outfits going from house to house (of the friends in the group) for further celebration and refreshments. The day in the truck is spent drinking, blasting music, and screaming in the street with obnoxious megaphones. There are huge banners all over the truck though I have no idea what's written on them. When the truck passes, everyone stops and cheers for them.
What a fun idea, though I don't get how they manage to stand for hours on end despite drinking continuously (though Danes do know how to handle their alcohol). It must be tiring too. I hear them from 4 blocks away screaming. I bet their voices are all pretty shot after this weekend.
Heres a closer picture of what it looks like. I couldn't get close enough to take one so here's one from a website (sorry for the watermark).
I feel bad for the poor soul driving that truck around for a million hours. Maybe he just wears earplugs.
