Quote - Did you have displacement set to any of the items that got poked-through? If so: disable all displacement settings on those items (and also on the model that is doing the 'poking')

No, it's all smoothing and no displacement at all. A bump map is the only depth given to the outfit. It's not an issue I have with all outfits, mercifully, but as a good number of my favorites are heavily meshsmoothed it's something I've learned to be wary about.
