You can get a tattoo anywhere on the body. You may want to keep in mind a few things though:

First, do you want your tattoo to be seen when you go to work? You might want to make sure the tattoo is in an area that you will not have to put extra thought into making sure it is always covered up for work.

Second, if you are planning to have more tattoo work done later try to have at least a rough idea of the complete plan for the area. This way you will prevent future design problems.

Third, larger tattoos are usually better as you will avoid having a lot of small stuff that eventually will be a problem to incorporate into a larger theme.
