The big problem with the (in)famous PhilC Leia / Oola costumes is they do not unzip as individual garments, but are 'grouped' to a minimal 'Vicky1'. Um, who has her now ? Finally, I remembered my other PC has a 'Vicky 1RR'. Retrieved, renamed, re-directed to Zygote, it allowed Leia to load. Then I selected and saved the garments ready for C-D conversion.
Unfortunately, anything without standard 'bones' --like wigs-- do not convert well. As the costume is so simple, I thought I'd try fitting it to Posette without conversion. Well, yes, scaled, tugged and tweaked, the set does fit where it touches...
As yet, the costume is non-conforming, but that's just Leia...
