Mursi woman with a child.Taken at their village in Ethiopia.
They cut their bottom lip at around puberty and install a clay disk. With time the size of the disk increases. It's believed the tradition started by Mursi tribe to avoid other tribes stealing their women. Basically, they tried to make them look ugly for others. Nowadays it's considered a beautification.
