Wasn’t the 12 months between kiddushin and nisuin in the time of gemara so that the kallah could look her best on her wedding day? (Lefarnes es atzmah btachshitin, if I recall?) Also, gemara says a father is required to buy his daughter things that will make all the bochurim jump on her (want to marry her on the spot).
Second, whoever came up with this angry G-d theory? If a kallah wears makeup at her wedding, does this angry G-d blow his top, blow his stack, or blow smoke out of his ears? Why worship an angry G-d when one can worship a kind benevolent G-d instead? I mean, really, whoever came up with this nonsense? Maybe they need to attend some anger management classes, so they wouldn’t project their own anger on G-d.
