Sometimes beauty is covered and thought to be hidden away from uncouth, unwanted, and strange eyes. This rarely works, for beauty will out and is much more often about how it is displayed rather than how much of it is so.
On the downside, this tends to lead repressive cultures such as the Muslim World to enact even more stringent restrictions upon how women are allowed to dress. Saudi Arabia taking this to the logically correct – look at the images above! – but vile conclusion that even a woman’s eyes must be covered if they are deemed to be tempting.
On the upside, with war with various nations in the Mid-East – especially Iran – becoming more and more likely, there’s the benefit of Arab and Persian war brides. And yes, this is not only a benefit or upside, it’s the only truly good – evolutionarily speaking – reason for a foreign war.
