Joint test for a jacket. And yes, it opens, courtesy of the magic of body handles. The tank top seems to fit underneath nicely.

I haven't actually done much modeling on the jacket yet, which is why it has no detail; this is simply a placeholder mesh with which I can experiment with the joint parameters. I wanted to see if I could make the sides of the jacket posable first.

Don't know if it'll make the final cut for clothing pack #1. Currently, the body-handle joints are sort of a kludge.
