To me, it seems a bit paradoxical to celebrate mitzvas tznius with a public ceremony. Can you please explain?
You could make the same argument, I suppose, about a wedding. There’s no reason the bride has to dress up in a fancy distinctive gown and be the center of attention. In fact, she doesn’t even have to be there at all. A kiddushin via a shliach is 100% kosher.
