With experience comes expertise—no one proves this more than Tilda Swinton. The actress (and accidental fashion icon), who stunned in a Schiaparelli dress and a bold red lip at the 2014 Radius Holiday Party (above), shows how to own a look into your 50s and beyond.

To give Swinton a radiant glow, makeup artist James Kaliardos dotted a superthin layer of luminous foundation all over her face and blended with his fingers.

You may be tempted to extend the fun vibe of the dress with showy shoes, but timeless dark pumps prevent sensory overload.
