Character's Breasts Melting through floor?

[Dielle]

I know the title sounds rather weird, I've attached an image or two to help. This is what I get when I take my PC's clothing off, it looks fine with them on. I'm trying to figure out if it's a bodyslide issue (I used the SMP as my outfit) or something else. I have CBBE SMP and Xp32 extended.

Have this as well. I suppose it has to do with the HDT-Smp physics or something. I searched google, found weird videos and obviously downloads from chiense websites?

 

I have no clue to be honest, but if anyone can clarify the situation for dummies, hey, would be cool. Until then no jiggle for me ...^^

Usually, "weird super extended body parts" is the result of a bad skeleton file. Body and skeleton must match.

 

"I have ... and Xp32 extended. "

You don't. Or you have some old version or something is overriding the correct skeleton. Can also be the case of "custom race" or "unique PC".

For anyone who is searching for the answer in future, 
DO NOT OVERWRITE XPMSSE OR SIMILAR MODS THAT ADD THE SKELETONS
