Give her a random name and be sure to write it as soon as you can and use it the rest of the time. Be consistent.

She has a random appeareance with blonde, brown, black, pink, blue, green or silver hair, brown, black, green or blue eyes, and she can be from really skinny to a bit chubby. Her tits go from flat chest to a boobs a bit too big for her age.

She would be very embarrassed if someone discovers she has no pubic hair.
