Depends on the girl, the situation, what the image/word is, exactly where it is and why she's getting it, etc.
In a long-term loving relationship, if a girl gets a tattoo of (for example) her guy's name in either location, it is the opposite of "trashy." It is cool, intense, caring, and committed. Sounds good to me.

Some women tattoo their breasts after a mastectomy/struggle with breast cancer, to put something beautiful where the scars are. I don't think that's trashy.
