This is from the 'Glitterati' clothing line designed by Olivia Ong, a senior design major at Cornell University.
Upper part of the dress - is made from cotton coated with silver nanoparticles that deactivate bacteria and viruses.
Hood and Sleeves - contain palladium nanoparticles that act like tiny catalytic converters to break down harmful air pollution.

Since a yew yards of this fabric will run you $10,000, this is not yet being mass produced. And is aimed more at workers in the Health field and the Army working in contaminated areas.
