The top left circle, there's really nothing there to tuck in, she's already a slim girl, just seem like a bad pixelated area. For example, look above the luggage where it meets the wall, it's pixelated there as well.
The bottom right circle could be distortion from the edge of the door being there, it seems like that leading edge from the luggage leading to her right leg is where the corner of the door is.
The bottom left circle makes no sense why they'd take that in, it's just her legs, she's obviously not overweight or anything, so it's probably nothing.
