I've followed Nerd's tutorial for making conforming clothing by importing a clothing item's .obj then using the donor rig in the setup room, but… As you can see here I copied a few morphs from LF to the clothing and they transferred but as I mentioned previously I'm trying to avoid the cleavage shrinkwrap problem so many conforming items have. I'd hoped that the LaFemme Clothing DEV figure had a modified "uniboob" version of the breast morphs that I could have copied the morphs from (this is what PE does with its clothing dev figure, for this reason) but apparently neither dev figure has any morphs at all in it (outside of JCMs of course).

In the longer term this approach to making conforming clothing from clothing for other figures has the downside of losing all the rigging morphs (e.g. open/close/adjustments) that heavily influence what I buy when it comes to conforming clothes. I can see using this for some clothing in a pinch but it loses a lot of functionality in the process. Thanks for the tutorial, though.
