* Upper back - Either on the left or right side near the shoulder blade area. You could get a single star or a cluster of stars. It's a great place to get a tattoo if you don't want it easily seen by others. The top of the back right by the neck area is also a great spot if you're wanting an upper back tattoo. A small star or cluster of stars would look great in that area.
* Lower back - The lower back is a great place for star tattoos, especially if you incorporate some kind of tribal design to go along with the curve of the back.
* Hips - A cluster of colorful stars looks amazing along the hips of a female. Another popular design is one single star on the left and right side of the hips.
The best ways to get ideas for any kind of tattoo is to look at online galleries of tattoos and to speak with a tattoo artist. Usually for a small fee, they can help you design the perfect star tattoos for your body and they can also suggest places where they think the tattoo would look best. Although, don't feel like you absolutely have to listen to them. Remember that it's your body and your money, so just go with your gut.
