@ptrope You mentioned retaining the original groups? With this outfit I don't think that is the proper option. Try with regrouping option. Yes, you will loose all of the morphs. Or look at the original dress and see how it's grouped and use the Setup Room to duplicate it. that way you should keep the morphs, if you had transfered them. V3 has buttocks, the dress doesn't and that is what is ripping.

I must remember to remember what it was I had to remember.
