I'm not sure this should be tagged as 2024 pokemon teraleak. I'm guessing that perhaps the teraleak had concept art of Rosa with the alternate outfit seen on the top right, but the artist already did a similar illustration of Hilda, and that outfit was already seen in pokemon adventures (see post #3823824 and other examples). There's no reason to assume it's related.

We used to just tag images with this costume with pokemon_adventures and call it a day, but maybe now we should consider just tagging it as alternate costume.
