I've thought of something, if she is Latin American she would be using American sizing which is different to ours. An American size 10 is a British size 14, which looks about right when you look at her photos.
This could be the case with this girl and then when you factor in she may have lied about her size to begin with and is an American 12 then this makes her a UK 16, looking at the pics i'd put her at UK 14-16
The wider question is why girls lie about their size so much on AW profiles, now if a girl is size 10 in some clothes and size 12 in others then I can see why she would quote size 10 but i've turned up to see a size 8 girl who turns out to be a 14, WTF
Some guys like a girl with some flesh on the bones and some guys don't so inevitably end up very disappointed and with a negative review on here
