Thank you for tracking down the dress @longtompot. I've been married for years and not in the market for a wedding dress, but I've just spent a happy half hour browsing dresses.
@Clueless1980 and @XingMing How lovely for the dress shop to help her out like that. It was as if it was made for her, absolutely perfect. I agree @Bleepbloopblarp that it looks better on her than the model.
@Littleshortcake I wonder if the River Thames photo was taken on a different day as a 'photoshoot' for the story, as the bride isn't wearing her dress and strappy sandals, but what looks to be white scrubs and trainers.
