Thinking out loud

[WEIGHT]

I have noticed this trend for a long time. A woman in a dress or skirt keeps her knees closed, with the exception of overweight or mature women, and then they try to bring their legs together. But as soon as they even take off their outerwear, and even more so their underwear, their legs immediately spread apart. I wonder what this is connected with, instinct or something else? And secondly, they feel confident in the most revealing swimsuit, but in the most revealing underwear they suddenly become hysterical.
