When I also picture Rosswiesse and Asia in those uniforms, I imagine Rose wearing a crimson Valkyrie armor with the same button top, tie and cape as Ravel and Xenovia. And for Asia, I see her also wearing the same top but with baggy sleeves, long skirt and a veil, kinda reminiscing her nun outfit.

But hey, just my guess. P.S: Is there a name for that button top they're wearing?
