In her home town(the one west of the forest) there is a clothing store run by a friend who will give her the clothes. IDK if a low sanity is required because I entered that town for the first time with low sanity(took the other way around and never went trough the forest) so a lot of the shit they were talking about went straight over my head. I would have liked to have visisted that town before my Alicia was already so corrupted

Drawback of having a game that is a bit too much open-world imo.
In general, I thought the corruption went too fast simply from all the constant groping. I know you can reset the corruption at any time at an altar but that seemed like cheating to me imo.
