Children can in fact be taught to appreciate true beauty over glamour. But it must be taught very deliberately. Nothing good in this regard happens by accident.
How do you want your daughters to dress when they are teenagers? Think ahead. Then dress them that way when you bring them home from the hospital after birth. When they are two days old, dress them that way again. When they are five years old, keep dressing them that way. And you must deliberately train them, explaining what modesty is. Nine year-olds can really understand it, too, if you take the time to lovingly teach them
And modesty can be taught anywhere in the world. The young ladies will attract a higher quality of young men, too.
