I bought this blouse secondhand from Japanese Mercari. I do not know the specific year if was made and it seems like it might be L size from trying it on compared to my other BtSSB blouses and the elastic feels good and not stretched out. If you have trouble fitting into BtSSB blouses due to them being a bit too small, I think this will work for you. It hangs off of my mannequin which has a 34.5 inch bust. The ribbon is ivory but the blouse itself is off white, so I think it has yellowed from age. It doesn’t feel like an ivory blouse at all, so the ribbon is a mystery!! The ribbon is easily replaceable though if you wish to do it. The blouse itself has no noticeable stains but looks used due to wrinkling. The buttons are flower shaped.
