Below, the Neutrogena talent ambassador exclusively reveals to Twist her top three rules to December 31st fashion:
Stay Away From Stilettos: "Wear cute wedges or low heels so you can dance!" Emma says.
Remember Accessories: "Don't be afraid to add a belt if a dress has a lot of volume," the actress explains. "I like belts from Topshop."
- Keep Warm: "Get a scarf that goes with everything and can be dressed up or down. It is the perfect accessory for a cool New Year’s Eve winter night."
As far as your beauty look goes, Emma recommends keeping it simple. "I am going to do a clean eye with just eyeliner and mascara, along with a stronger lip," she says. "I am loving wine-colored lips for the holidays."
Her go-to shade? Neutrogena MoistureSmooth Color Stick in Rich Raisin, which she calls "the perfect pop of color." The American Horror Story: Coven star also swears by the brand's Healthy Volume Mascara, since it doesn't flake. Noted!
