There's nothing wrong with keeping it real simple, and that's exactly what Keri Russell showed off in spades in LA yesterday. Dressed in a breezy white button-up shirt, denim ankle-cut jeans, and tan-colored Worishofer sandals, the low-key starlet proved that even the easiest of pieces can make an effortlessly polished and, in this case, totally classic style statement. The key to Keri's spot-on look was her impeccable attention to details: the tucked-in shirt, the preppy tortoiseshell sunglasses, and the subtle addition of a few gold bracelets all contributed to a strategic juxtaposition of undone-meets-refined styling. We think it's the perfect off-duty combo that — with a quick patent-leather heel and tailored-blazer switchup — can transition into an any-occasion ensemble.
