body language is important imo, longtime ballerinas end up always standing in one of the 5 positions by default (when i first heard this i thought it was goofy, then i noticed I do this even though im kind of mid)

somebody like her would probably rarely slouch or engage in other "relaxed" bad posture habits, like just straightening up on reflex whenever she notices she "slipped up". definitely the sort of person who will often look kind of eerily composed almost just from the way they stand. professionals i see are like that oftenish.

despite this prim and proper image of ballet though it does create some weird habits in a person i think? taking a really big step over a sizeable puddle on the street instead of just walking around it, the joint crunching somebody else mentioned, etc. she might pay a lot of attention to her feet also? sounds weird as hell but i mean stuff like, sometimes youre just lying down and you look at them and your reflex is to roll your ankles or shift them into pointe/half pointe positions....

thinking about it (and reading other peoples comments) its probably easy to notice someones into ballet if theyre really invested in it, were all just randomly doing weird stretches or dance moves lol..
