jimbeach, well I managed to fix my problem and it works in daz studio. 

Here's a pic: Margot"s( v3 character) Body + MIKI"s head( Frankesteined) and the  dress is Hongyu's Jersey Dress.

I managed to make it work after a long tedious battle with  converting the Jersey dress to my Margot character.. I don't know why but I used Wwizard 1 long time ago, and converted the dress but recently i've tried to use the same dress and it just wouldn't work anymore. I guess POser went crazy. But i kept trying and finally the dress worked. 

Anyways, that was in Poser.

But when i opened the dress in DAZ Studio, it  worked!! I'm happy!!!
