While I really, truly admire the kind of creativity and ingenuity it takes to design and make a wedding dress out of TOILET PAPER... I'm thinking this probably isn't the best choice a bride-to-be could make for her actual wedding dress. Nervousness making you perspire? Toss the bouquet a little too strenuously? Dancing a little too energetically at the reception? All recipes for disaster if you're wearing a paper dress.
Besides... do you really want a flushable wedding dress?
