A fine of up to 10,000 euros: Some costumes are prohibited at carnival. If the view is obstructed, a fine of 10 euros is possible.
If there is a danger, this may also constitute a violation of the general duty of care and result in a fine between 20 and 35 euros. Neither freedom of hearing nor freedom of movement may be restricted by a costume. It's clear: opulent disguises with a full-body head-body mask are not allowed.
