Bethany and Miranda
Bethany and Miranda are two Simlish sisters who opened an underground tattoo parlour and turned it into a corporate empire. They commissioned a portrait for the cover of their company's annual report but it became so popular they released it to the public. It is purchasable in The Sims 3.
Not much is known about these two sisters. They are not in the actual game and only are described in the description of their poster.
