I just googled it. I think all the designers did a wonderful job, except for Marchessa (Ariel). The dress fell flat, beautiful color, but otherwise quite plain and failed to live up the sketch. When I saw the sketch, I expected the dress to have a few similar colored trains, not one same colored train. I also don't think Harrods did a great job showcasing Snow White's Oscar de la Renta dress. They posed her true to her character, but covered up the bodice, which looking at the sketch was the most interesting part of the dress.
I loved Aurora's Elie Saab dress and Mulan's Missoni dress was the most well executed. I also have a soft spot for Rapunzel's Jenny Packham. The final version differed from the sketch, but for the better. I have admired Jenny Packham's designs since I spotted them on the Duchess of Cambridge (haven't we all), but I admired them for the classic designs not because of who wore them. I wish I could afford them!
