Fernando Brizio - a portugese artist -  created this stunning dress as part of the Turin-based exhibition “flexibility - design in a fast changing society” last year.

The dress has little pockets and by placing coloured felt-tip pens in them, the appearance of it changes over time. Since the coloured ink bleeds into the fabric and creates a one-off design each time. After cleaning it, the owner colour it in a different way for each time they wear it.
