Sometimes skins in the "Town Folk Skin Pack" will be glitched to where random pixels will be set random colors, both in the skin customizer and in game. This hasn't happened to me prior to this update. To get/fix this you have to ether enter and exit your world till it fixes, or open and close the "Classic Skins" part of the skin customizer, because the skins effected are random, in the screenshot I added the "Miner" skin is the only one effected, but other times other skins will be effected. I'm not sure if this bug effects other skin packs.
