Calista Montgomery is a pre-made unplayable young adult mail carrier introduced in Sims University from The Sims 3: University Life. She can be made playable by marrying her, or asking her to move in. .
Calista is a level ten rebel and has completed a degree in fine arts. She has no skills at the start of the game.
It is ironic and possibly a glitch that she has the Can't Stand Art trait yet she has a fine arts degree.
