I had to do a bit of research but I think that the main problem is that this item is so old that it was made to fit the old base. If you take a look at older backgrounds with cutouts, there is a white space next to the hand. Not AS bad as the dress but I think it is the same issue. It was just made for the old base. When I try and move it, it creates white space on the other side. If I move it over and up it is a bit better although I think only a redraw will fix it completely.

That being said, I can see if they will be ok with moving it over and up until that happens.
