She has made numerous TV appearances and is now under production with the film, "Chaos Theory". Constance Zimmer tends to be an actress that looks familiar.
Constance is wearing a simple hairstyle. The feathered frame around her face is sharpened with hair wax as you can better recognize by the placement of her bangs. Wax was used to gather small sections into points rather than allowing the bangs to hang freely as is done traditionally.
Ms. Zimmer took an easy route with her long hair by gathering it in a low riding ponytail that she then braided. It’s possible she french braided her hair as it’s difficult to determine in this picture. Either way, the tell tale sign is the long plait you’ll find draped over her left shoulder if you look closely enough.
