The pictures are definitely size 14. Is she bigger in person than the pictures?
problem with this is its opinion based going off flattering photographs, & talking in dress sizes isn't really touching on the facts (measurements with a tape measure).... as you can be a size 14 in shop A and a size 18 in shop B and neither of the two in shop C.
Bottom line is shes a large unit, and the photos are extremely flattering they do not show the true extend of the gut, thighs, arms etc. Which isn't to say its all a bad thing, all WG's do it (show the most flattering pictures), she's still a good fuck and decent looking I think.
