She has red/orange hair, purple sunglasses and wears a pink track jacket with pink track sweatpants.
A mean, rude and bossy old woman, Aunt Ivy seems to delight on making people wait on her hand and foot. She is shown to make constant unreasonable demands of Jon and treats him like a servant, yet denies his most reasonable requests. (i.e. getting out of the bathroom after two hours so that he can use it). While Garfield hates her as much as anyone, he likes having her around. Apparently, it makes the other characters feel more appreciative of him ("Compared to [Aunt Ivy] I actually seem easy to live with").
Despite being cruel and abusive towards her nephews (and to an extent, her other relatives), Aunt Ivy does show love and affection to her daughters.
