I've tried to play today and seems is working for me,here are test renders which I've done 

I've used morphing brush/tool with smoothing(Magnitude 1.0) on the zig-zag'd gartebelt lace straps and then I've used Morphing tool with Tighten Fit(I think I've used 0.0010 for pokethrough margin,Radius 0.0288,Magnitude 0.5)

Hope this help

Thanks,Jura
