The tightest pants seem to be worn by professional ballet performers, male and female. (Not that I myself am into ballet, nor do I have anything against those who do, just in case anyone is wondering.) There was even a scene from the 1984 comedy movie called Top Secret!, where some male ballet dancers were lined up in a row and someone was walking along their bulging male packages. It was exaggerated, as it was of course a parody, but it served to illustrate just how tight and blatantly revealing the pants are which are worn in ballet performances. Here is a link to a really short excerpt (under two minutes) of that scene – the part I’m referring to begins at 1' 20":

For those who would be so inclined in the powder-puff category, all I can say is, forget about watching the joggers – just try going to the ballet. (Not that I myself am into, um, “powder-puffery,” nor do I have anything against those who do, just in case anyone is still wondering.)
