Interesting to me on the netiquette angle, precisely because, even though she herself now agrees it was warranted in this case, what I saw in the initial story was the commenter trolling her. She was basically posting flighty-ditsy-social-celeb news, basically p.r. for her brand as an actress. In that context, what is supposed to be a lighthearted, take it or leave it celeb feed, (i.e. this political troll barges in and raises get serious all you Marie Antoinettes fiddling while Rome burns.

She gets it now, she really gets what she bought into with this marriage: no more celeb fun and games. And even further, gets that she has to be apologetic and properly old WASP style discrete about the high society stuff--she did a pre-emptive on the ball gown.

My netiquette point: if an actress had done this on a feed about what wardrobe she was chosing for the Cannes film festival, other commenters would consider the commenter a troll. I.E., Occupy Wall Street hippie drops by to disrupt our whole conversation.

We've got this sort of solved about first ladies in a strange sort of way. They get to do the celeb thing with clothing but they can't comment about it themselves, though fashion journalists can, it's like this: they are just forced to wear all this fancy stuff to promote the fashion industry. I recall that Rosalyn Carter turned down that particular role.
