Though she plays the dressed-down badass Fiona Gallagher on Shameless, in real life, Emmy Rossum cleans up nicely. The actress/singer, who also stars in this month's fantasy drama Beautiful Creatures and has a new cover album, Sentimental Journey, switches between elegant, ladylike dresses on the red carpet to low-key separates when she's off-duty. Whether she's dressing for a step and repeat or a latte run, Rossum highlights her figure in feminine silhouettes supercharged with bold colors and intricate motifs. The outcome? A polished sophisticate with youthful flair, making her the darling of both the fashion and film worlds. Click through our slideshow for her style essentials.
