"It's one of those childhood things. You grow up watching Cinderella, you want a tiara and to sparkle," she said.
The dress she bought for her January wedding - not the one she wore for our picture - reminded her of marshmallows and pavlovas: "It's a meringue."
But how does one find such a gown? For Williams it was in Henderson at Colleen Aalbers' store, Ballgowns, Bridal and Beyond.
Aalbers said many customers were talking about the show. "Barbara would be one of about three people in the last six weeks that have come in and said, 'I want a big boofy dress.'
"We get these young ladies come in, they want something slinky and slim, then they try on a princess dress and they go, 'Hang on a minute, I want to be princess for a day.'
"I always say, 'You are a bride one day of your life, the rest of it you are a wife'."
Aalbers encourages customers to fulfil their dream on their wedding day.
Auckland Roma gypsy Jiri Demeter said the TV weddings were similar but more extravagant than in his native Czech Republic. But he did concede that puffy dresses were popular in his culture. "The puffier the dress, the wealthier the bride's family," he said.
