you've been duped breh
what you know about playing with pants placement and shirt placement to make things seem like they are ... bigger. gonna go into internet-loser "i bang 9/10s lol" mode here. that girl is alright face-wise, cute, but probably a few pounds away from being fat. in those pictures you posted, which i assume are the best you could find, despite this her maximum allowable curviness (IE appearance of being in shape but is on the edge) she wears her pants up to her belly button to create illusion of having an ass. could also be to hide that gut. no stomach pictures is basically concrete proof.
i bet you look at her instagram you will not find one normal picture of her standing straight with her whole face showing without fukking with lightning, or angles, or other such devices. much less of her in a bikini or something.
6-7 ranges manipulating things that look like 9s breh, its a standard case
so finding a slightly overweight 6 on the street would be a relatively simple get.
