Is it the outfit in your gallery? Not sure which bits are problematic.
Having owned a number of leather purses and other types leather goods with raw insides, it has a tendency to get burnished over time, just plain rubbing/ handling will smooth it out eventually. Never tried to do that on purpose or quickly, but it's entirely possible you could get a smooth stick and some vegetable oil and just plop down in front of a long movie (or several) and manually rub out the sueded surface. No idea how long it will take though.
