Online retailer NET-A-PORTER taps actress Emma Watson to star in a shoot for its weekly digital magazine. Talking to the magazine, the British star reveals the dilemma in finding eco-fashion, “I’ve always had this huge problem. I would love to wear garments that are ethically sourced, but there aren’t enough options for me to be able to do that realistically.” That’s why in the images photographed by Bjorn Iooss, Emma wears all looks from the Green Carpet Challenge, a range of designs that are eco-friendly designed by Christopher Kane, Victoria Beckham, Erdem and more available exclusively at NET-A-PORTER.
