Emma Watson using her powers for extreme goodness. Her dress was a collaboration with Calvin Klein and Eco Age and is made from recyclable materials. “The body of the gown is crafted from three different fabrics, all woven from yarns made from recycled plastic bottles (!). Plastic is one of the biggest pollutants on the planet. Being able to repurpose this waste and incorporate it into my gown for the #MetGala proves the power that creativity, technology and fashion can have by working together.” Love this.
