Why does my clothing lose it's rigging on upload?

[freudianslaps]

Hi everyone!

 

So, I made a cute little dress in marvelous designer for the kemono mesh avatar body. I load it up into blender to rig it to the frame, then remove the avatar dummy base so that I can upload it into SL. When I mess with it in SL, the rigging is on and I just have a static mesh that attaches to random body part. I've been working really hard to learn how to use these tools, but I seem to be stumped here. Can anybody help?
