phonehome,
a) stats on bra sizes are completely worthless for a number of reasons, and using them as any basis for your assessment is a bad idea
b) even if the average size was a "c cup", that doesn't mean that there aren't millions of women above that size. You understand that the population of the world who actively uses social media to post photos is enormous, right? Should we be posting all the pictures of people who aren't busty in an effort to convince you that these people are unique?
c) go outside and actually look at people, then you'll see
d) your judgement on breast size only increasing because of weight gain is just plain wrong
e) Tiffany Towers' breasts were somewhat squishy but didn't look natural.
From reading your post, it seems like you've made up your mind, despite all the evidence around you, so I'm not really sure why you'd choose to even participate here.
