- duplicate layer
- top layer, greyc -dt 150 -p 0.6 -a 0.5 -alpha 1.5 -sigma 1 -gauss 0.8 -fast -alt
- top layer, -dt 80 -p 0.6 -a 1 -alpha 1 -sigma 1 -fast -alt
- bottom layer, -dt 200 -p 0.8 -a 0.6 -alpha 1 -sigma 1 -gauss 0.4 -fact 2 -fast -alt
- bottom layer, -p 0.8 -a 0.6 -alpha 0.5 -sigma 1 -fast -alt (subtle, just reduces noise very slightly)
- mask away the top layer over the frills, blush, etc.

The main (top) filtering still shows some screening, but it's not very intrusive. If I bring it up further it starts to smear a lot of edges.

If you're looking closely, the graininess of the bottom layer is visible. To get rid of that I'd have to filter the bottom layer more, which would just start to blur out the frills again, and it doesn't seem too bad.

I posted the layer mask (post #65772); maybe it'll save someone time if they want to try something similar. I didn't spend time cleaning it up. In Photoshop, create a layer mask, alt-click it and you can paste it in.
