It's a morphed version of Judy (which comes with a lot more morphs than the default version.) The mesh uses V2 textures, again, better than the default Judy does (especially the eyes.) For clothing, you'll need to use items intended for Judy unless you're good with the Tailor or have some other way of adapting V2/V3/Posette clothing for her. Fortunately, there's some great stuff for Judy around, e.g. at PhilC's site. This is a very fine product, I wouldn't be using Judy at all without it.
