Up-and-comer Amber Heard is growing on me. With classic bombshell looks and a rebellious streak, I’m positive the self-possessed actress is one to watch, on and off the screen. Especially after her latest ensemble caught my eye.

Shopping at The Grove in LA recently, she whipped a slinky yet breezy BOSS Black dress into a strong day look (no easy feat when high, cascading slits are involved). I’m digging the combo of a high-drama maxi avec easy flats and a belted cardigan – so chic, so organic. Especially when topped with of-the-moment round, tortoiseshell frames.
