The Bride - the wedding dress already drenched in blood:

The girl who is supposed to be pure before consummating the marriage is no longer a virgin and the blood that is supposed to be on the wedding night sheet covers her dress.
The truth is outed “to the displeasure” of the rabbi, the witnesses and the prayers – the men who conduct the ceremony.
The lower attire found in the “upper” layer of the dress implies to a more complex identity of the bride.
