So modesty is evil and anyone espousing modesty is bad, alrighty then.
Seems that is the case.
While society plays some role in determining what is modest, some things are almost a given.
At one time, showing ankle was risque. Now it’s nothing.
But there are certain areas of the body that really are not meant for public display.
That said, knowing that men are so easily enticed by the human female body, it behooves women to dress in a way so as not to cause an undue burden on a man who is tempted in that way, or in a way so as to embarrass children. And mature women will take that into consideration. because they are not so self-centered, callous, and narcissistic as to not care how what they do affects others.
Butt cheeks showing are certainly NOT necessary in any sport. It’s not like there is the issue of *drag* in the water or some other performance issues. There is plenty of choice in sportswear that is designed to keep one cool and dry while competing in hot conditions.
With what they are wearing these days, one equipment “malfunction” and there’s a show for all the world to see.
