I was wondering about bone weight painting. It seems the old blender had an option to paint on all faces, but 2.63 got rid of that option.

How do you paint your weights evently on the outside and the inside of a dress?

Here's someone who is having the same problem. Maybe she explains it better. community.secondlife.com...

So if you make the outside layer first, then weight it, then extrude inward, the weights will be on the inside too?

And what if you have details like a belt or buttons? These have a clear inside too and they're floating above the outside fabric.

So when you paint over them, the part of the fabric underneath them doesn't get painted.
