It's good to see some more things for Bella! I have added the dynamic dress to my wishlist until the weekend. :)

 

Quote - Just learning to model here..but I'm working on this one.

my big challenge is uv mapping the neckpiece.  I may have to take the medallion part off and do it as a separate object, then put them back together in poser.  

I can't quite see how the necklace has been created but you should be able to uvmap it all together. You can hide the dress by selecting it and pressing the control and h keys in Silo while you work on the necklace. Nice job on the dress!
