There are ways of increasing the size/length of the labia minora.
African women have been doing it for ages, so I am told. They hang weights of suitable size at the bottom of them, which in time stretch them. It takes maybe years to get the result desired, but if a girl begins at 13 years old, she would have labia of suitable size by say 16 or seventeen years of age. It is not Less drastic is by having her lover or a lady friend to suck regularly on them. There are sites which show labia minora that are so long that they are in the way during work and walking. Don't go to extremes and don't use a doctor's scalpell!
