Butterfly rib cage tattoos are a form of body art that has become increasingly popular in recent years. They are usually large tattoos that cover the entire rib cage, though they can also be as small as a single butterfly. They are a great way to express your inner beauty and creativity. The design of a butterfly rib cage tattoo is typically very intricate and beautiful, with the wings of the butterfly often being a major focal point. They can be done in a variety of colors, though the most popular are black and white.
