I didn't scale the crop top this time. Crop top collision offset is 0.4, collision depth is 0.1.

For it's 0.3 for both collision depth and collision offset for the pinafore, which I think is what odf recommended.

I also changed the parent of both clothing items to "universe." IME, dynamic clothing works better if it's not parented. Unless it ends up on the floor, I don't parent it to the figure.

There are still dimples in the straps, but the spikes are gone.
