Saoirse Ronan in Lanvin

Saoirse Ronan in Lanvin

Who: Saoirse Ronan

Where: A screening of “Brooklyn” at the BFI London Film Festival at the Odeon Leicester Square.

When: Monday, October 12th

What: An embroidered silk gown and crystal and flower necklaces from Lanvin Pre-Spring 2016.

Why: There is always the risk of looking seasonally inappropriate—or worse, bridal—wearing a long white dress in the chilly months. Ronan avoids both disasters with clever makeup and heavy neckwear.
