You could make that argument, but it's partially true at best.
Olympians wear whatever the fuck works best because they care more about that than looks, which is why the swimming full-body speedsuits came, until they were banned.
But swimmers still wear one pieces without porny cuts even though a super-high cut might be better.
Serious athletes wear the best gear they can 95% of the time, and frequently what is best seems to be "maximum exposure of skin after support considerations."
My wife was an NCAA rower and she wore itty bitty bikini bottoms and a halter bra.
