I remember anna has four routes split into two types, the love and slut routes, There was an image of anna in a wedding dress, then the outfit with tan apron, the revealing black and white outfit, and then the pink lingerie, does anyone know how to get the pure route? aka the wedding dress anna, I've done three playthroughs where ive carefully made sure not to get a single slut point in interactions but i always end up with the other love outfit for anna. is it not out yet?

As far as I've seen is part of the anniversary gift for her when you share her with Adrian and Joseph, Joseph invites you to their room where Anna is in her wedding dress and then you have an anniversary foursome, maybe it's also in the endings but as far as I know you can't actually use it yet, I think that image was just a way of presenting her routes
