I didn't realise Halfpenny posted the photo of Lydia in her dress. The fact she put her dress on, got made up, took photos, sent them to her designer, no doubt asking to publish - because she knew how ridiculous it would look if she posted them on her own insta! THIS!!! this shows the level of her delusion and insanity, and insane jealousy of Victoria. Victoria and Leonie are the girls she aspires to be, but she will never be them, the only thing she can be is as thin as them. She knew her wedding 'content' was nowhere near as good or professional as Victorias, and she probably realised that she had not maximised her content, never thought to do a making of the dress video or anything else. Your true character will always come through, however much you dress things up or talk about who and how you are. All these little 'tells' just show her mental decline.
