These are Fernando Brízio's renewable clothing.
I think this is cool - not so much for dresses, but something else - curtains maybe.
The idea is that the dress is constructed with pockets into which washable felt tip makers are placed, the markers bleed and create a pattern on the dress, and then it is washed and the process starts over again - not sure how renewable that is, but it's cool.
If you google him you will find that her works a lot with bleeding ink.
