Who: Carey Mulligan

Where: The ASMALLWORLD gala dinner for the Alzheimer Society at the Gstaad Palace Hotel in Switzerland.

When: December 15

What: A silver and black tulle dress from Valentino fall 2012.

Why: The geometric lines of this delicate silver overlay keep the dress black tie-ready, not tinsel town. Sleek pulled-back hair and minimal makeup are the perfect, umm, foil.
