Esther is one of the girls in Wendy Testaburger's extended gang. She has never actually had a very prominent role, but she does often speak in the episodes which heavily concern the female students. It can be speculated, due to the similarities in their appearances, that she and Kevin are twins. Her surname may be Stoley.
She has shoulder-length black hair, and wears a sky-blue jacket with pink trimming, and pink trousers. She wears pink gloves as well. Under her jacket, she has been shown to wear a sky blue blouse (as seen in "Rainforest Schmainforest").
As a "stupid spoiled whore", she wore a green-and-black military patterned halter top, blue jeans, and black stiletto-heeled boots. She also wore pink blush with blue eye shadow, similar to Rebecca.
At the sleepover in "Marjorine", she wore a violet pajama top with a deep purple lace collar, and a pair of violet plaid pajama bottoms.
