I think my slutty Hello Kitty costume idea was used. It was mentioned in this blog. (please notify me if the pictures are not to be used. In that other blog)
This "Happy Kitty" costume is pretty cheap. It's only the dress, and I think the leg warmers. It doesn't even include the hat! It's sold separately! I'd buy the hat and the bag by itself. They are cute. That mannequin kinda creeps me out.
Disclaimer: The pictures I used on this entry are not watermarked and I forgot where I got them. The one with all the Hello Kitty costumes I got from a newspaper.
