I'm watching a repeat on Watch. The bride didn't like the dress the groom designed for her, so they rang him up and told him to buy another dress.
So basically, she chose her wedding dress anyway. Which isn't the point of the show, really. 
To be fair, she does look lovely in the second dress. I bet the other brides were sat there watching it, thinking 'Why didn't I just kick up a fuss too!'
