I don't think Wisp means to be rude, it's just that while there are MNetters who like to and can spend good money on clothes, there are also people on here who are trying to get by all year on £10,000. Not that that means you can't post, just... don't be surprised when people make the odd comment on spending that much money on a dress.
I think most of them are a bit too white and wedding-y for my taste, and I can't quite picture how the hangy skirts work with a bump? I picture then sticking out more! I'd be more tempted by this, as I think on a big bump tight dresses do actually look better.
