Rigging Clothing Issue

I made bodysuit and fitted it with Transfer Utility. (Top part of suit and Genesis's Pelvis are hidden for better view)
But I have a problem with rigging in the crotch area. The pictures shows the problem area after fixing weight maps. That's the best I could do.
Moreover, when I cleared all weight maps the problem is staying.
I don't know what else could affect suit geometry.
I'll be very appreciated for any help
