My fantasy would be Amy Lee with her hair in pigtails, wearing overalls with a shirt, pink velcro sneakers, and a thick Tranquility diaper underneath. Also, a pacifier in her mouth.
A little too detailed, I know. I have a thing for older girls looking and acting like little girls. Something about it that is so darn cute(maybe I'm just weird). Plus, Amy Lee is the prettiest girl I know of, she also has an amazing voice.
