That’s the ideal covered/uncovered ratio. It is science:
Women who revealed around 40 per cent of their skin attracted twice as many men as those who covered up. However, those who exposed any more than this also fared worse…. The study, published in the journal Behaviour, found that the most popular women combined the 40 per cent rule with tight clothing and provocative dancing. The 15 per cent that combined all three criteria were approached by 40 men each.
That sounds reasonable enough. I tend to prefer something more on the order of 65 percent visible myself, but then, I’m not as easily threatened by the thought of competition as most men are. And, of course, it also depends upon the shape of that which is being exposed to the light; there are terrible forms better suited to mad Lovecraftian visions than night clubs that no man wants to see uncovered.
And it’s good that the researchers picked up on the tight thing. I am still amazed that women in the early 90s thought the baggy grunge look worked for any of them. You’d think they would have noticed that the man who popularized it married Courtney Love. All that oversized and baggy clothes do is make a woman look fat and insecure, even when she isn’t.
