Some people choose to get initials or names. This is not a good idea, unless you are getting the initials or names of your children or perhaps a deceased relative. Getting a tattoo of a lover or spouse's name (or worse, face) is almost like a curse for the relationship, just ask anyone who has one. If you must have your beloved's name inked on you, consider going for Asian alphabet characters.
There are designs that look beautiful on women. Flowers are very popular, but not just your run of the mill rose. These days, ladies are getting exotic blooms in bright colors, often with black tribal designs behind the flowers. Zodiac symbols are also popular and can be done in a variety of ways, from plain black to outlined and filled in with solid or gradient color.
