This is a culture of female display. And the reason it's a culture of female display is that on the Upper East Side women far outnumber men, if you do the sex ratios. I can't say exactly what they are, but you could google it. People have said two to one. So, it's a female display culture because sex ratios are skewed toward men, and they sort of have their choice, even if they're married.... Also, women are economically dependent on men, and so there's that aspect of needing to perform your beauty and your scarcity.
