Nah man, as much as I would like to believe it, it is clearly AI, a very good AI btw, but still AI.
Like, pay attention to the gold ornament below the laces, it becomes smaller and smaller as she untangles the string. And also the strings are hanging in front of her but suddenly they make a pop sound as if they were stuck lower, she starts untangling them by pulling the loops instead of the tips.
Her right nipple is slightly more up when she removes the fabric than it was while covered.
Pains me to say the video is AI. But the detail of her nipples was very well done , based on other photos and videos where she partially shows Aureola and nipples through sheer fabric, the nipples really look like hers. I'd like to know which AI they used.
