Don't Miss:

We loved how Emmy Rossum’s bold magenta lip contrasted her metallic gold Donna Karan dress at this week’s Critics’ Choice TV Awards. “It’s a fun color,” Rossum told InStyle.com of the hue, the Rouge Dior lipstick in Star Fuchsia. “I didn’t want to do a heavy eye because it’s summer.” Vivid lip hues like this one create an instant polished look, even if you choose to go light on eye makeup like Rossum or skip it entirely. Shop the color for $30 at dior.com.
