I am looking about and wanting to look at some 3rd party figures and wondering if this one's any good. Also, are clothes and hair from other figures compatible with this? http://www.daz3d.com/little-one
I know you can purchase the figure support files for Wardrobe Wizard from PhilC. Works well in the stand alone or plugin versions of WW.
I believe XDresser offers a license for this figure as well.
As will all conversion software, conversions vary from mesh to mesh.
She'll need her own clothes and such, but there is a crossdresser plugin for her, it looks like, that would let you use clothing from nearly any figure on her. Hair you can always parent to the head instead of conforming.
Some of 3Dreams hairs come with fits for her.
