Dash, that is not what I said. I said if the kallah’s father is a talmid chacham then you should stand for him when he enters the room with hiss daughter.
Confucious, exactly. If it is the kallah walking down with the mothers then my reasons wouldn’t apply unless you say “kallah domeh l’malka” (I don’t know either way whether we say this so I won’t comment either way). There is also ZK’s point that she is on her way to a mitzvah so you should stand for that.
Either way, I don’t think there is anything wrong with standing for the kallah (as long as you aren’t doing it to get a better look) but I also don’t know whether there is a chiyuv.
