Heart tattoos are one of my favorites and usually mean love, love for a person or object or even love for yourself. You could also decide to mix the heart symbols with other items to show love of a particular thing. This is pretty self-explanatory as hearts are romantic symbols which are said to exude human emotions.
What makes heart tattoos a good choice for women is the many different ways you can display them, not to mention the variety of symbols that can go with them. For instance, if you are a Catholic you might consider getting a sacred heart tattoo. These are usually well shaped and realistic looking hearts, surrounded by thorns and displayed with a cross drawn down the middle. Another example would be a puzzle heart. This tattoo is used mostly by married couples, but can also be used to show friendship, or a bond between parents and children.
Since hearts are usually symbols of everlasting love, many women choose to wear a design that is small and red, with the name of their lover drawn inside. Try not to regret this design down the road. Although, its not unheard of redoing this style as broken heart. You can come back later and put jagged strike down the middle, to symbolize the loss of your lover, but can still keep the tattoo to show your personal feelings toward love in general.
Women also like to use the literal style heart tattoo. Like a symbolic heart, these look realistic and carry more meaning to women in the medical field, or ones who have struggled with illness. If you like, you can lightened this design up with cartoon shapes, or jazz it up with loops and bright colors to have it not look so dispelling.
So choose a your style with deep meaning and love, or something purely fun and sexy, but choose wisely and have fun.
