Exactly the same for me. I've had to change the hair to something shorter. Anything that goes past the outfit's collar or rook's shoulders has this problem and the less bulky the outfit, the more pronounced the problem becomes.
I know the patch had a "fix" for long hair and armour issues but it's baffling to me that it's been listed as a fix when it's so obviously made things much worse.
It's so frustrating because the hair physics were one of my absolute favourite things about the game. I hope it can be fixed soon. My Rook isn't the same without her long hair :(
