Cecilia Tallis's green dress from Atonement is the epitome of glamour—at least that's what I thought when I first watched it in high school. The bright emerald hue combined with the elegant silhouette made it instantly iconic. This ruffled green dress is loved by nearly every girl who has seen the flick. Now you can capture the same star look at an extremely low price at Mislish. Just shine like Keira Knightley!
