Attached Link: Jean-Luc's V4 stretch chest morph

Jean-Luc, a friend of mine, made this V4 chest morph for one of my comic heroines to fake her wearing a skintight catsuit.

Like Joe@HFG said, the morph had to be made for a specific full body morph or else if say I dialed down 'voluptuous' it would change the whole chest effect.

But, if someone were to sell such a product that had chest stretch for different chest sizes... I bet that would sell like hot cakes :)
