Leanne has platinum blonde hair that is similarly styled like Luanne's, albeit messier with light brown roots, radiant peach skin, a curvy body and wears bright red lipstick. She is seen typically wearing a hot pink crop-top that shows off her midriff and blue jeans, paired with dangly earrings. She has a heart-shaped tattoo on her left breast. She claimed while drunk at her engagement party that she was "only 34," though she is likely older.

When sober, Leanne seems to be a bubbly woman.
