I've tried scaling up the pinafore to 102% before simulating. That seems to have worked nicely to fix the crinkling in the front with the recommended collision settings from the Readme (see image). So, that's now my "official" recommended fix, at least for the time being. :grin: With larger collision offsets, I imagine one would have to go a bit higher with the scale-up.
