In a live roleplaying game, the more effort every participant makes with their costume, the better the game becomes for everybody. By costume we don't just mean your character's clothing, we mean everything your charater has - any weapons and armour, as well as any props or set dressing that you bring to the event. The more convincing these things are, and the less modern items there are visible in the game, then the more immersive and real the event feels for everyone.
