I mean… I don’t think wearing clothes at all, and thereby covering beauty, is a sin (though you could argue that the way we do it, for propriety rather than pure adornment, celebration, and comfort, it is a consequence of sin)

I DO think “covering” personhood is a sin, and I can’t help but see the progressive swallowing up of women in more garments, so concurrent with their being swallowed up in oppression, as symbolic of that. 

But I believe the sins here are exerting control over other human beings. Tyranny, gaslighting, and spiritual abuse. 
Saying “dress this way or we are entitled to attack you” and “dress this way or you are sinning” and causing women to reduce themselves in order to survive is the evil here, not simply clothes.
