Yeah, it would be nice to have new clothing options when Monica achieves a certain corruption level. Or maybe some minor physical changes, like piercing, tattoo, or new hair style.
Too bad it probably won't be implemented. Partly because it will increase the number of renders to make. Partly since it would be silly for Monica to look one way in one branch but totally different in another, especially when the brances are not separated.
Also it is obvious that Fashion Business is the least important project for the developer now, and his attention is focused on two other more profitable games.
