There are a few different things that people might mean when they talk about V lines on a girl. One common meaning is the line that goes down from a woman's navel to her pubic bone. This particular line is often considered sexy and attractive, and many women work hard to make sure it is visible. Another meaning of V lines can refer to the shape created by a woman's hip bones and lower back when she stands with her legs together. This type of V can also be considered sexy by some people. Finally, there are some women who have a small indentation or v shaped dip in their lower back, just above their buttock cheeks. This area is sometimes called the venus dimples or the dimples of Venus. Some people find this area to be particularly attractive as well.
