About the headgear: Danish tradition dictates that students upon passing their last exam be presented with a 'student cap' (bought and paid for in advance; whether you follow the tradition is voluntary, though).

This bunch have maroon bands, so it's the academic branch, and many will no doubt be starting university in the autumn.
