There are so many ways we teach the language of Attire to our children. We teach it first by example, of course. Our kids learn about what is mete and good, from us. They learn a good deal of it too, from the media, naturally. But far more importantly, they learn how to speak the language to each other in their play time together.
What it also allows them to do is fix in their minds all our culturally accepted notions of gender roles, and potential career choices. So, seen from a point outside, that can be a detriment. But it is the ultimate source point for each of us, as adults, for all our often rigidly held ideas about what looks good, what can and should be worn, and by whom. The internet, in fact all the various media are full to the brim with people who are only too ready to tell us what does, and does not work. The rules get reinforced constantly, and they start in our childhood.
