Karlie Kloss has jumped on the rainbow hair trend—and is giving off some major sea siren attitude, at that. Last night, the supermodel posted an Instagram from the set of an upcoming project in Paris, captioning the photo, "Mermaid vibes on set," accompanied by the appropriate emojis. Kloss has previously switched up her length, alternating between her lob and layered bangs, but this is the first time we can recall her playing with dramatic colors. We're definitely feeling it, and the coordinating blue liner is a pretty nice touch, too.
