Look at the video of her running, posted on September 29. A video posted on September 27 also shows short clips of her standing or walking or sitting with knees bent, showing that her femurs and tibias are proportional length. There’s a video called rapture prep posted on September 22 that includes a thumbnail that is a side shot with her knees bent, showing the ratio of femur to tibia.

I think it’s a normal proportioned short person whose camera angles tend to lengthen her upper body and shorten her lower body. And maybe a preference for high waisted pants that may trick the eye into thinking the hip hinge is higher than it is.
