Ok, so maybe this is old news (Oprah and Elle beat me to it) but it is right up my ally (2 different people sent me articles). Enough qualifications, check this out:

I’m quivering with amazement. That my lovely readers is a GROWN dress, grown from the pure cellulose microfibrils produced by certain bacteria during the fermentation process. The idea arose from a serendipitous conversation between creator Suzzanne Lee and material scientist and biologist Dr. David Hepworth. The bacteria are fed a solution of sugar, green tea, and yeast. 

A layer of flexible cellulose forms on the top of the liquid mixture after about a week of eating and “spinning”. This material can be shaped over a three dimensional mold or dried flat and used for cut and sew. The final product handles much like a vegetable leather. Jackets are one of Lee’s first designs, and tote bags are currently being investigated for mass production. Brewing processors may be the key to scaleable production, with their extensive fermentation knowledge and large facilities. 

Aside from pure awesome-ness the cellulosic mat is also eco-friendly, as it is produced by low energy means and biodegradable. (Unfortunately products are not yet available to the public, sad Materials Girl.) Go right now, check out Suzzane Lee and her Biocouture site, and have your mind blown.
