It's almost Earth Day, and Kate Bosworth already has the most essential look. With just one day to go before it's officially Earth Day, National Geographic has already had quite a busy week — last night, its new documentary series Genius debuted at the Tribeca Film Festival, and the previous day, the network held its annual season preview, the Further Front event. Bosworth will star in The Long Road Home, Nat Geo's new scripted series based on Martha Raddatz's book of the same name, alongside Sarah Wayne Callies and Jason Ritter — among the channel's first forays into dramatized series. So it was that casting that brought her out on Wednesday, along with actors and screen personalities like Morgan Freeman, Katie Couric, and Jane Lynch, who all came out in support of the event. In the middle of this quite politically minded crowd, Bosworth came through with the most on-point statement of all: a grass-green Rochas look, because Earth Day.

Who: Kate Bosworth.

When: Wednesday, April 19.

Where: The National Geographic Further Front event, where she supported her new series The Long Road Home.

What: A grasshopper-green Rochas dress with a box bag and shoes, also by Rochas, and jewelry by Arzano. She also opted for side-parted hair and a dark lip.

Why: Bosworth makes the treehugger look edgy with a wine-colored lip and a slinky silhouette. Her Rochas look is a muted tone of the Pantone color of the year, greenery — and we do love a star who has her finger on the Pantone pulse. Bosworth adapts nearly an entire look from the Rochas Fall 2017 runway, foregoing just the knee-high stockings with which the look showed on the runway. And in the process, she disproves the age-old Kermit the Frog adage: When you've got the wardrobe of a Hollywood actress, it's actually pretty easy to be green.
