I really hope that is the case.Hmmm i don't thing that's what it is tho. Seems more like a photo mode where you can't fit and pose the girls, in the menu or something (like a characters/models viewer in some games). I don't think it's gonna impact the game what so ever.
Having a customized gallery (i.e. "clothing simulator") as a means to view the renders they've already made via their Patreon clothing polls is a lot more palatable than an "app" that allows the player to choose what clothes the LIs wear in-game. I still think it's unnecessary eye-candy, but it wouldn't severely impact development time once set up.
In my rush to judgement, I interpreted the original posts on here as the greater of the two evils.
