A dynamic dress (for V4; but...);

and a pair of super-conforming "Platform Slides" (shoes) for V4/A4/G4; but I bet Posy will get them to fit her easily enough.

I haven't tried the dress,yet; but I did give the shoes a quick lookover...; they work very nicely!

Oops... I forgot to post the quickie test image...:

Thanks for the link!
