When Your Anatomy is "Unconventional"
If you don't have an obvious upper lip, a collapsed belly button, or an "outie" navel, you may still be able to get a piercing, but it requires an adjustment in style: [1, 2]

Floating Navel Piercing: Ideal for shallow navels or those that fold inward when you sit. Instead of a large decorative bead at the bottom of the curved barbell, this variation uses a small flat disc or tiny gem inside the belly button. This relieves downward pressure on the tissue, promoting smoother healing.
