Josephine Doherty spent two hours getting into the £25,000 dress to marry her fiance, Tom Delaney, in Tolworth, Surrey.
It took eight best men and five bridesmaids to carry the 60ft train.
It took her 30 minutes to get into her Cinderella-style horse-drawn coach for a four-hour trip to the reception - where the cake had 40 tiers.
According to The Sun she said: "I had always dreamed of a fairytale wedding."
Her gown beats the 25st dress record set by Carly O'Brien, 16, in Gloucester six weeks ago.
So now it's 'Lets see who can be more stupid than Carly O'Brien? time'
