Bring the girls out - a friendly and informative guide to big boobs in k-pop

After reading several astoundingly informative articles on Anti Kpop-Fangirl lately, I thought I'd better step up my game and not lose pace in the blogging information war.  So here it is - the k-pop boobs post you've all been waiting for/dreading.  I will perhaps never again deliver a post containing this much raw knowledge.  You are now about to benefit from my exhaustive research into the topic of female boob-appreciation, so I hope you appreciate it.
