Can you share what that discussion about robes was about?
Er? you mean her clothing?
If that what you mean, basically it was examining the way she dressed in each game and how it ties into their themes.
So for the first one it was agreed that she should appear "care free" and sexy to attract players. Some feel her appearance might have been changed now if they developers had known how successful this game was going to be. Suggesting they might have toned her outfit down if they did.
For the second game, her appearance is a LOT more "casual glamour" and in this sense is meant to match her hooking up with an AV star, like she belongs in that world or the world of entertainment in general. Personally I felt it was also meant to show how her "experiences" have changed her and yet is just her casual self too but more owning her sexuality in a casual way.
The opinion was while her outfit in the first was sexy it was more next door sexy, her outfit in the second game is more like SHE knows shes sexy in a cougar kinda way and comfortable in it.
Now the THIRD outfit for the last game is interesting BECAUSE originally it WASN'T the current one we have - its actually a modified version of her second outfit to make her look older but basically the same (honestly I remember seeing it and it looked the same lol but okay...) then they updated it only this month to the new one. There is some conversation if the new scenes of her in her new outfit (in-game) where added much later in development.
Now clearly this is by far the most conservative outfit shes worn - the conversation was basically its so she appears to be a domestic older "wife' in a very plain fashion. Hence fitting into her role as the rented wife (looking the part) vs her more open and sexual clothing from previous games which show a women who has a kid and comfortable in her hyper sexuality.
Going back to the previous statement there is some discussion of a re-write possibly to expand her "role" as a rent wife beyond just sex but as more a true domestic wife which wasn't in the original script but further expanded on.
More so its VASTLY different then anything shes worn before or for her characters personality. So there is some question in that going back to she dresses like this to APPEAR as a wife but in a "different" life then the one with Kenji.
In my own opinion IF they are right in this regard, it might also explain her prequels which might end up justifying WHY she choices to go back to her first boyfriend aka first love where she feels more like a "wife". I also think her third outfit it so make her look slightly older as to represent her aging game to game since they cant just give her wrinkles lol.
Honestly I'm really disappointed now about the prequels games, although they might also be the first true "love" games Atelier has made under THIS label which is kinda interesting - if they are INDEED love themed games with no NTR or such then it will really make players wonder why she married Kenji at all.
Which has me thinking that perhaps they won't be, maybe her boyfriend just wanted her for sex and "trained" her for it as such. We see he uses bondage in one screenshot from Marina 3 so perhaps their will be a lot of bondage play in the prequels.
