She has medium-length hazel-coloured hair and violet eyes. When Beatrice leaves the convent, she is seen wearing a orange dress with a orange-ribboned hat. However when at the convent she is seen wearing the same uniform as the other girls.
Beatrice is a kindhearted girl, as well as calm. She explains to Cosette why the girls at the convent ask a lot of questions, so she is also very helpful.
