I picture
Alice as having red hair and freckles. She would be a book-worm, obedient, friendly, and nice, but with a smaller group of friends. She might not be particularly fantastic at anything, but
Alice would probably play a sport, play an instrument, and do well in school.
Eloise would have dark hair and light eyes. She would be quirky and eccentric. She would have plenty of friends who flock to her because she is the best at coming up with something to do. She would be a little bit tomboy but a momma's girl. Probably likes to cook or knit or do ceramics. Not the best student and not quite an athlete and for sure her head would be in the clouds.
Olivia would be a typical girl. Pretty, popular but not overly popular, happy, likes to dress up for dates and dances, reads girly magazines, likes pop music and singing in the car and shower. Would be a good older sister. Would always get her work done for school, even if she procrastinated for a while first.
