Sara White is of average height and build for a 15 year old girl. She's a tomboy, so she keeps her hair cut relatively short, and typically dresses in jeans and a grey zip-up hoodie. She's got the trademark red eyes of a hybrid, but her hair, which was once dirty blond, has faded to almost white. A thin network of scars (think the encroachment look from the Eva TV series) runs up the left side of her body, the top end of them reaching just up to the very bottom of her face on its left side.

The closest character model I can think of would be Chie from Persona 4, in terms of body type and hairstyle.
