Emma Watson's Met Gala dress was made out of recycled plastic bottles

Emma Watson made a statement on the Met Gala red carpet: Fashion can be both elegant and sustainable.

Watson was participating in the Green Carpet Challenge, and on Instagram, her stylist, Sarah Slutsky, explained that the five piece look crafted by Calvin Klein was created "from three fabrics woven from yarns all made from recycled plastic bottles. Plastic is one of the biggest pollutants — being able to turn this waste into a high quality material is a real success story."

Slutsky said the outfit was designed so it could be repurposed into several different ensembles — the pants can be worn on their own, and the train can be used again for another red carpet event. The zippers were made out of other recycled materials and the inner bustier was created using organic cotton, The Telegraph reports.
