Women of the Kayan tribes identify themselves by their forms of dress. Women of the Kayan Lahwi tribe are well known for wearing neck rings, brass coils that are placed around the neck, appearing to lengthen it.

Girls first start to wear rings when they are around 5 years old. Over the years the coil is replaced by a longer one and more turns are added. The weight of the brass pushes the collar bone down and compresses the rib cage. The neck itself is not lengthened; the appearance of a stretched neck is created by the deformation of the clavicle.
