Eisdell relied on the NARS Light Reflecting Loose Setting Powder ($34) to ensure Mulligan's complexion glowed without getting oily. Apply with a fluffy brush all over—especially under eyes immediately after concealer—paying special attention to the center of the face.
A dusting of Sex Appeal (blush!) on the apples of the cheeks was in order—the light shimmer gives off a luminous effect, while the soft peach color played nicely with the pale pink of Mulligan's dress.
Calling to mind the common Gatsby-era beauty staple, Eisdell drew an ultra-precise Cupid's Bow in a color that matched Carey's lip. Using NARS Jungle Red Lip Liner ($22), she sketched her outline. (It's easier to do so with gentle, downwards strokes, building for intensity once the shape is mastered. Make sure to step away from the mirror periodically to check for symmetry.)
Eisdell finished the look with NARS Semi Matte Lipstick in Jungle Red ($26). For true, bold color payoff, apply with a concealer brush and fill in with a lip brush as you get closer to the line. (Q-Tip touchups will be absolutely necessary.)
