We are punjabis of kashmiri origin and in our family it is "STRICTLY" forbidded for women folks to pierce their noses which is quite normal for all other punjabi tribes among whom we live in. I never understood this anomaly in our case but my mother told me that this is the defining feature of a "kashmiri" that their women will never ever pierce their noses. All the women in my extended family and relatives (all kashmiris) are without nose piercing.

Does anybody else also has such custom in their families or some knowledge regarding the background behind this particular custom?
