Laws against women's nudity were at he time a solution to the problem of men fighting over women and using sexual harassment of women to goad men into fighting (putting the onus on women's for men's weakness of self-control). We carry those laws forward in culture without looking at their origins. Both men and women denigrate women who dress 'immodestly', whether that means dropping a veil or going nude. It's only a matter of degree, and Westerners who regard the burqa as oppressive need to look at their own mindset about revealing clothing and nudity worn by women. There is no justified cultural superiority in that.
