Yes, I also have noticed men's shorts getting longer and women's dresses getting shorter. As Confucius said,this means that rape is becoming difficult , because "woman can run faster with skirt up than man can with trousers down." Aside from that, the ones who could attractively wear short skirts never seem to and the ones whose attributes would be better concealed do.
As in other matters, I completely ignore fashion and continue to wear short shorts, provoking accusations of indecency and embarrassment from wife and son. Swimming togs and men's underwear generally are also becoming longer and floppier. To put it succinctly, I prefer clothes which keep things held in place, especially during athletic activities, and this pragmatic consideration overrides fashion as far as I am concerned.
