That doll's not a Kirsten, she's a "Girl of Today" (what they use to be called or "Just Like You" (what they're called now) doll. They don't come with names, so you can name them whatever you like. Kirsten's, no matter how old, have blonde hair and blue eyes. You can get a JLY doll in practically any hair/eye combination, so if you like, you could get one with brown eyes. It just wouldn't be the one AG's named Kirsten at that point.
