it's like she gained weight only around her jawline. Originally I was trying to find reasons that she may not have gained weight, that the differences we're seeing are simply because of what she's wearing and the lighting. The longer I stare at this picture, however, the more I see that she's put on weight. I'm going to start from top to bottom here to justify my thinking, but if anyone thinks otherwise I'm interested to read what you have to say.
Her forehead and hairline look relatively comparable, not too different.
She's obviously caked on makeup, but I think that whatever foundation she's using actually makes her face look fatter. the shadows on her cheeks in the first picture make her look thinner, (at least to me). covering them makes her face look like a giant blob.
Her nose and lines around her lips are what convinced me. Either she's retaining water or gaining more. Her nosering does look tighter than it did on the first picture, (maybe we can take bets on how long it'll be before that thing pops right off?). The mouth lines do look a tad deeper as well. One could argue that this is because her mouth is closed in the second picture, but the crease on the left side of her mouth, (our left), is definitly deeper.
Lastly her jaw. It's absolutely wider. Not by much, but by enough to be noticeable. She could have her jaw sitting in different places in these two pictures, making her extra chins appear differently.
but her mouth and nose are what convinced me of a recent weight gain
