Well for Irina for I'd guess it be the same as Xenovia's but with longer shorts covering her thighs, kinda like how they wore their respected Church battle attire.

But for Bina, I don't know her that well so I can't rule out her choice of fashion, all can assume is she wears the same button top, tie and cape as the others.
