Im as shown in David's many paintings, resembles a typical Grey alien: gray skin, a large head, and large black eyes with blue pupils. However, Crescent also appears to have long, straight, jet-black hair that goes down to her shoulders. She typically wears a long blue gown of sorts. When disrobed, she appears to have flesh-tone skin like a typical human, as well as large human breasts. Huggins claimed that on her planet, she was "one of the large women".
