Don’t worry too much. This is entirely beyond your control, and if people bitch at you, remind them they’re most likely playing a pirated, modded version... and that they’re doing their bitching on a forum that caters to pirates and modders.
Doomyk provided the solution. He forgot to mention that you also need full charisma!
I don't know the exact oder but I had to go back as I thought I had to threaten her the first time I came across it. There is an option to make her more open to the idea with invade mind/remove inhibitors. Then choose the try to convince here two or three times but with a day of time in between. This got me there iirc.
Scroll to the top of the page, type charisma into the search box at the top right, and hit enter.
They were just costumes I wanted to use in the game in some way but could find no justification for, except as novelty costumes for Belle. I'll probably add a leather outfit for her at some point, but it's obviously not a priority.
Why exactly are you concerned about Belle's costumes when you have a perfectly good no costume option? Since no one else can see her, what's the point of making her wear clothes since she obviously prefers life without them?
