In honour of Earth Day, Kate Bosworth amped up her evening look with a moss-green mididress adorned with cascading pleats from French designer Rochas. A crystal-embellished, miniature cross-body bag, bedecked pointy-toe pumps and diamond chandelier earrings from Arzano give the look an overall glamorous feel. To top it all off, Kate wore a vampy, aubergine lip and sleek, straight hair.
