Kate Beckinsale arrived at the InStyle afterparty in a '60s-inspired light pink strapless dress by Gucci. Soft ruffles extended from her gown's sweetheart neckline — which was all the dress needed to recall mod style — in a minimalist way. A midcentury-inspired collar necklace and gold box clutch added extra shine to her look, while her hair and makeup stayed in line with the throwback feel of her post-awards ceremony outfit. Do you think Kate's look is Mad Men cool?
