Wasn't the jacket on over her shirt?
I mean... the one they sold her in is pretty much what she wears in the webisodes and that's what people will want. For a background character, I don't see much interest in a beach or other themed version. Another version probably won't cut it for some people and there's not really any way they can release her in the expected suit without people complaining that their exclusive isn't exclusive anymore.
I sort of expect this move from Hasbro as they thrive on fan tears and seem to enjoy making unique characters as exclusives, but I kind of expected different from Mattel. Regardless of her being a non-speaking extra who sometimes pops up 2 or 3 in a single crowd(which I guess is irrelevant- Rochelle's not even shown up at all). Now Hoodude, they could make a new one that's not so plush- the one they made is quite a bit off-model and too bulky. But they probably will not.
