Who: Diane Kruger.
When: Tuesday, August 9.
Where: First, with director Alice Winocour for a talk about their new movie Disorder; then, at the film's New York premiere.
What: A Valentino bomber, button-down, and lace skirt; and an Alexander McQueen dress with Chopard jewels.
Why: Kruger does the day-to-night transition flawlessly — and makes it look easy while she's doing it. First, a street style-ready outfit composed of pieces with varying tones. Her bomber eases the preppiness of the striped button-down, and adds a bit of edge to a romantic lace skirt. For her night look, she opts for a statement McQueen dress in broderie anglaise with billowing sleeves and a wrapped belt. Oversized Chopard earrings top off the whole thing, and there's not a false note in sight.
