Tattoos for Women

What are the most popular tattoos for women? I seem to see the lower back tattoos the most often, but that does not appeal to me at all. I would rather have something small and more or less hidden. I would also like something a little bit original, so it would be nice to know the most popular designs so I could choose something different rather than just following the crowd. I’m sure heart designs, butterlies and flowers must be popular, and I know of a bunch of people who have gotten Chinese characters with different meanings. What are the other popular designs?
