While watching the final season Mad Men, we couldn't help but notice it: Sally Draper (aka Kiernan Shipka) has the best bold eyebrows. We're not sure exactly when Sally's enviable arches sprouted, so we rounded up images of the young Draper through the seasons. In the first few years, she sported dirty-blond brows (and adorable want-to-pinch-them cheeks), but as Sally grew into her looks, so did her eye frames. Currently, her strong milk-chocolate arches pop against her honey mane and make her big brown (often pouty) eyes stand out. Plus, in real life, Kiernan changes them up for the red carpet by toying with the brushed-up brow trend. Relive her top beauty moments through the seasons, and check out how those arches keep growing and growing and growing . . . Watch out, Cara Delevingne — we see some eyebrow competition coming!
