Kirsten is such a cute doll. I love her little braids, and a lot of her collection. I find her books a bit more on the boring side (save for a few which I love, like her meet and Christmas books), but I'm half Scandinavian, so Kirsten and I have similar ancestry.
Rating: I'd give Kirsten an A, though I must admit that's simply because I'm not a fan of her meet outfit without the accessories. That aside, for *just* the doll, I'd definitely give her an A+.
She has pretty, bright blue eyes, and my doll, has a plump, though not as plump as PM dolls, face with nice, sandy blonde hair that's really long, and nice for playing and styling.
I've never seen a PM doll, so I cannot comment on the differences, but the M one is very pretty.
