Jokes aside, I did big boobs version too. I aligned the top of the breasts with nsbcx's so that I thought I could use those bras for this body but...
clearly there's major gap in the back. Although the top positions are the same, the bottoms are much lifted compared to cx, it may look more natural than that, still it's silly huge tho. I haven't decided I should keep this halfway compatibility, so I'll share this later.
