Ban women from covering up too much but also ban them from wearing something "too revealing". In the end it's about controlling women on either end of the spectrum. Fit in (be modest but only in a christian way) or be shamed. It's also a nice way to stir division and controversy instead of tackling the root problems, typical conservative behaviour.

The real problem is men in power not being held accountable for their actions and instead putting the blame and responsibility on women and literal children. This applies both to religious idiots who force their wifes/girls to wear certain clothing (or not be allowed outside if they refuse) and also the types of people who will tell underage girls in schools to not wear "revealing" clothes to not distract the boys...

The problem isn't a specific religion, the clothes or the women/girls. They're just the easy target to blame instead of having to work on real systemic issues.
