If you look closely, her upper lip is maybe a 1/4 of an inch thinner in the old pic... but if you look at other pics, it's not thinner at all. It all depends in the way she's holding her mouth, as I showed with the newer pics.
Her lip here at 13 is exactly the same as it is now. Maybe she had fake plastic lips and noses that she just took off and put on when she was in the mood for something different.
Notice her nose here is shorter and fatter than it is even the very next year. Must be magic.
