The Beer Dress is made from fabric produced by a bacterial-fermentation process. Scientist Gary Cass and visual artist Donna Franklin previously collaborated on a fermented-wine dress in 2012. That dress had a distinctive look to it, like it was made from Fruit Roll-Ups. The wine dress looked strange, slightly alien. The Beer Dress looks more like what we recognize as typical fabric, despite its unusual origin. You wouldn't know where it came from if someone didn't tell you.
Well, it sort of resembles a frothy head of beer too.
