Regardless of weapon choice, everyone carried a dagger. Daggers are used for more than just being a weapon, they actually make sense on every outfit. Daggers are more akin to a shoe than they are to a weapon.
I personally believe that advanture outfits with a dagger on the side makes more sense than a ball dress with high heels. But that is just from my point of view.
Daggers the best part, needs 10 more daggers!
