This is my render result with the fixed obj file. I think that position of the buckle is sufficient to see. Each part must be very small because of Pippin's size, though...

The buckle has a high mirroring value. Thus the surface of the bootie is reflected in its side. Then, it may have been seen as to be in a deep position. I thought so.

Incidentally, this is a report.
I don't know which version of Poser everybody is using. I use Poser 6 - 9.
The command of "Conform to (Fit to)" does not work with Poser7 or DAZStudio. It must have a description of the same bone structure as Pippin in its CR2 for Poser7. You can copy the description of Pippin's CR2 if you are interested in it.
And old Poser users (or DS users) have to set the materials by themselves.
But they can use the item by parent-izing manually. I think probably that is not a difficult work for a Poser user.

I especially love the elaborate design of the Jet Pack. Very COOL :)
