To me, it seems a bit paradoxical to celebrate mitzvas tznius with a public ceremony. Can you please explain?
Actually, the mitzva that the gemorah says requires Tznius is a wedding (once again, Succah 49b).
also i dont recall that he has to talk with her all the way to his house, i thought taking her was sufficient. do you have a source?
The husband can have his Sheliach accept the wife from the father before two Eidim. The Gemorah talks about “Masar Ha’Av Lesheluchei Ha’Baal” in Nedarim (10th Perek, as well as other locations in Kesubos IIRC).
