My understanding is that in the Muslim faith, women are often seen, wrongly, as chatels and the property of whichever man takes priority, first the father, then the husband or the brother when the father dies or the uncle or the cousin or whatever.
The men regard a single male as predatory on their "property" which is why they make them dress them so that their atractiveness is hidden or at least subdued. Hence the famous "honour killings" that sadly happen.
Whether that can be seen as an inferiority complex or not, I don't know.
This isn't strictly true, see this.
But a lot of Islamic men do seem to mis-interpret their view of Shaira law
As for what they must wear.
"The
Kingdom of Saudi Arabia formally requires Muslim women to cover their hair and all women to wear a full-body garment, but it has not been strictly enforced.
[135][136][137] Saudi women commonly wear the traditional
abaya robe, while foreigners sometimes opt for a long coat.
[138] These regulations are enforced by the
religious police and vigilantes.
[138] In 2002, the Saudi religious police were accused by Saudi and international press of hindering the rescue of schoolgirls from a fire because they were not wearing hijabs, which resulted in 15 deaths.
[139] In 2018, the Saudi crown prince
Mohammad bin Salman told
CBS News that Saudi law requires women to wear "decent, respectful clothing", and that women are free to decide what form it should take.

All very interesting. Not surprised your wife doesn't want to get involved.
