This model is a bit special. The breast bone is scaled 0.75 times. Also, the thickness of the legs is scaled 0.9 times. The clothing is not given a vertex weight for the breasts, so they cannot be bounced. Increasing the Blendshape value of the clothing will restore the original breast size. ---------------------- [Notice] Package for costumes. Avatar data isn't included.
