For the 2016 Met Gala red carpet outfit, Emma wore a dress completely made of recycled plastic bottles, almost entirely. That time, Emm shared in a Facebook post, “”Being able to repurpose this waste and incorporate it into my gown for the Met Gala proves the power that creativity, technology and fashion can have by working together.” She added, “Plastic is one of the biggest pollutants on the planet.” She also explained that from the zipper to the organic silk lining, everything of the dress was environmentally-friendly.
