Remove a Moire Pattern from Clothes?

Get the Adjustment Brush (K) from the toolbar, and then click on the + (plus sign) button to the right of Moire Reduction to reset all the other sliders to zero and set the Moire Reduction amount to +25. Now, paint over any areas of your image that have a visible moire pattern (this often happens on clothing with thin lines in the pattern, like a sports coat, or patterns on luggage or camera bags, where you see a wavy pattern appearing over an area that pretty much messes up everything [as seen above in the Before image]). You can just “paint it away” now (and it usually works pretty remarkably well). If it doesn’t go away enough, increase the Moire Reduction amount by dragging it to the right (as I did here).
