Cindy Lou Who is a sweet young girl in How The Grinch Stole Christmas. In the original children's book by Dr. Seuss, she is a minor character, but she becomes the secondary protagonist in the movies. This guide features her costume from the 2000 live action adaptation starring Jim Carrey as the Grinch and Taylor Momsen as Cindy. Around eight or ten years old, Cindy lives with her frazzled father in Whoville. Unlike the other Whos, she believes there is some good in the Grinch. Later she sneaks aboard the Grinch's sleigh and helps him return all the gifts. Cindy befriends the Grinch and brings him to celebrate the holiday by singing around the giant Christmas tree. Cindy also sings  "Where Are You Christmas?" which was specifically written for that movie.
