Though Sisters don't often wear the stereotypical habits and robes, so you probably won't even notice them anyway. This is just where I am though
Obviously they're usually not nearly as young as most eastern media depicts - nips just like it because of the whole 'purity' thing they have going on, making them young just adds to the appeal.
