For me a wedding dress has to fit the bride's personality and style. While there are endless beautiful, even stunning gowns, they are unexpected, surprising (not in a good way) and often awkward.
Princess Letizia's gown was a work of art, but she seemed to be engulfed by the high collar of the gown which just made her seem like a turtle hiding in a shell. Princess Mette-Marit's gown was soft and romantic and very feminine and she looked so delicate but it did not reflect her very down to earth and practical personal style.
Princess Victoria's gown was a triumph of style over glamour. It's clean lines and style imitated Victoria's practical style and yet she looked so very regal, but I doubt very many would have been able to carry it off. HGD Stephanie's gown was very simply styled and reflected her serene nature while still being a stunning masterpiece. Yet once again I find myself thinking that few of her contemporaries could wear it to the same effect.
