>>2360023USA does not have the biggest breats in the world, not even close. Especially not if you take only Caucasians as a group. Among those USA is far behind several countries including the UK, Germany, and Australia. If you go further to just "whites" you have slavic women from Russia, Ukraine, and Poland who commonly reach sizes that in the USA would be extraordinarily uncommon.
The biggest breasts of all are in the Dominican Republic, Haiti, and other places around the Caribbean. I'm also starting to see evidence women from Ghana and Nigeria are extremely huge. Some black women in the USA also reach bigger-than-basketball sizes on bodies that are not overly obese.
In short, that image is just bullshit.
