Quote - The skirt gets all screwed up and that little silver bar sticking out from her back shows as part of the gloves when I click on it, although the gloves look fine. How do I make it not do that? My best guess it that it's a rigging issue where the outfit is trying to follow the shape of her body but I have no idea how to fix it.  I've tried "restore selected item pose" but it doesn't do anything like it does when I get strteched body parts on a pose. 

Yes, the autofit has weight-mapped it to the leg bones on the assumption it is part of a full skirt (although, even if it were, this would not be nice). In reality, this front panel would not move with the legs to any great extent. Fixing it is a job and a half, involving weight-mapping and possibly even modelling corrections. There's an early DAZ video tutorial series on this here. Some of it may be out of date, but it gives you an idea of the issues. Autofit seems pretty much useless, or at best hit or miss, for all but close-fitting garments, and has issues even with these (like shoes, and items with bits of topology it doesn't like). Not really sure if the improvements in 4.5 will materially effect these problems.

I had the exact same problem with this garment for M4/H4 (the figure is Genesis):

The front and rear flaps distorted just as in your skirt. I fitted it by parenting only and adjusting with the morphs. Whether this will work depends on how comprehensive the  morphs are in the garment. In this case, they were excellent.
