For the record, the "accusation" is that the promoter of these vile exhibitions would occasionally walk into the girls dressing rooms and when he did so, he SAW THEM IN THEIR UNDERWEAR (presumably bra and panties).
These are young women who, a day or two later, would be walking down the aisle in public wearing 2-piece bathing suits made of, essentially, dental floss. So they are horrified that the promoter of the event saw exactly as much flesh as they exposed publicly, enthusiastically, during the course of the exhibition.
Like a lot of the accusations leveled against Donald Trump, this is bullshit.
And some of you people need to figure out what a "pervert" is. Enjoying the sight of beautiful young women partially clothed is not perverse. It is what rational people consider normal.
