I don't know if there's any going back now. Bob has stated that there's no mandate on the posing trunks - they can wear the old school ones that actually cover something if they want - they prefer the string bikinis though it seems.
Notice when most of the pros hit a lat spread or something - they actually reach down and hike up the thongs even more

I guess in an attempt to show striated glutes, but who knows. It's disgusting and they should be marked down. No way this will ever happen with the current judges - they voted Kai as best poser. He should be shunned and the type of displays he puts on should be discouraged. Like it not, there are women and children that attend these shows - it's not gay porn.
