Bra and Clothing Bounce Differently? Help.

[Adamasin]

So I'm using the Nuke Western CBBE Bodyslide from the Nexus, and there's an opening where the nipple pokes out. Now, I'm trying to find a balance between lewd and not, so I equipped some underwear-- from various different mods-- vtaw, lacy, etc.-- and the issue I have is that when my character moves there's a bounce difference between the clothing (body) and the bra (accessory/armor). It causes some major clipping and drives me absolutely nuts. 

I've included pictures of stationary (little to no clipping unless she starts doing an idle of some sort), Jumping (massive clipping with the outfit, less clipping with the body itself), and turning (the worst offender.)

How can I fix this?

Because its weight is not 100% consistent with the weight of breasts on your body.

or

Its polygon number is far lower than that of your breast, so it can't deform synchronously.

Any way to fix that?

Would it work if I were to try to splice the bra to the other mesh, or is there a way that I can modify its weight in NIFskope?

I suggest you take a look at this tutorial first.

There are parts involving modifying tools and weights.
