My mother, AH, was niftar 3 days before my scheduled chasuna. The mesader kiddushin paskened that the wedding could be held after sheloshim and that it was permissable to have a band.
The wedding was postponed until immediately after shloshim?
My father sat shiva when I got married. (Makes me sad to think about it.)
He was allowed to attend my wedding with certain limits and Halachos. My Sheva Brachos he wasn’t allowed to attend until Shiva was over.
What limitations did he have at the Chasuna?
