Believe it or not, these glorious dresses are all fashioned from white and limited-edition pink (!) Cashere Bathroom Tissue.
They were designed especially for the 2009 Fashion with Compassion Gala in Canada, a "fund and awareness-raiser for the Canadian Breast Cancer foundation."
You can see more of the designs and read about the event here, at The Daily Thread.
It is amazing what you can find when you google "pink bathrooms"!
