I havent since I stopped wearing soft pants. It's not an easy way to put on jeans since the fabric isnt too stretchy or flexible.
In any case, that's the motion I mean. They detailed it a lot in that scene where she's talking to Shinkurou about to go out. So to rephrase it, I wonder if they're just pandering to pedos or if they happen to have a fuckton of budget to throw away into little details like these. I do know they did some pretty awkward animation for ep 6, so it might as well be the same thing.
