My twin sister called me the other day as she often does from an airport waiting lounge. She had a three-hour layover at Heathrow, en route from Norway to LA. In between sips of champagne, she told me all about the fashion campaign she shot in Norway, the various fjord locations, the stylish and super talented New York-based crew she worked with--and, of course, what they wore. "The stylist, the art director, they were all wearing green--army green, olive green, pea green, khaki green--just green! It's the new color," she affirmed. So when I spotted all the mossy hues coming down the Spring 2015 runways (at Derek Lam, Peter Som, J.Crew, Jason Wu, 3.1 Phillip Lim, etc.) and on New York City streets (Harper's Bazaar editor Amanda Weiner, above, in a pretty verdant print today by Michael Kors and blogger Sabrina Meijer, below), I wasn't the least bit surprised. My sister has already cashed in on this emerging trend with this cool pair of cargo pants. I'd like to go green with this classic Equipment silk button-up blouse, this Burberry belted coat or this Madewell, this Jonathan Simkhai circle skirt, this H&M ribbed turtleneck or this luxe Givenchy, this snake embossed Rochas clutch, this Burberry Prosum layered ruffled silk dress, and these Matt Bernson pointy-toe flats.
