Beyond Skin, a U.K.-based vegan footwear company, provided Kurylenko's shoes, which were comprised of Dinamica, a faux suede made entirely of recycled polyester from plastic bottles and polyurethane fibers. Beyond Skin partnered with People for the Ethical Treatment of Animals (PETA) to start selling the metallic-trimmed evening shoe on March 3.

Twilight star Kellan Lutz wore a textured black eco-tux with cerulean accents by New Zealand-based H Brothers designer Jomnarn Dul. H Brothers created a limited edition line of eco-tuxes each made of up to 25 recycled plastic bottles from an eco-fabric known as Repreve. It's a part of a partnership with EKOCYCLE, a joint venture from musician/eco-tech enthusiast will.i.am and the Coca-Cola Company to help brands make sustainable products from post-consumer recycled materials.
