The "Gloomy Fox" outfit is currently available for Witch, Sorceress, Valkyrie, Maehwa, Kunoichi, Mystic. I don't see why it should be exlusive to those. Ranger, Tamer, Lahn, Dark Knight, Guardian, Nova, Corsair, Drakania, Woosa, Maegu, Scholar and Deadeye should also be able to wear it.

This would please anyone who wanted the outfit on their class AND it would generate more revenue for Pearl Abyss.

They could over all make Halloween outfits like gloomy fox or ram horn witch available for all female classes.

It's unfair that few of them has doubles or triples and others are stuck to 1 same outfit offer since 9 years xP

Yes. And there's probably also still some non-Halloween outfits that are only available on older classes (I don't mean the class-exclusive ones). I think this could be rather easily changed. It's quick money for PA, so please do it.

Yes and Ram Horn Witch.
