She's come a long way since capturing our hearts as lovable ditz Karen Smith in Mean Girls. Since then, she's taken the leading lady reins in Dear John, Mamma Mia!, Letters to Juliet, Big Love, Red Riding Hood, and In Time. At only 26 years of age, Amanda Seyfried has proven a force to be reckoned with on the big screen and on the red carpet. And for all her fashionable feats, we are completely wowed by this birthday girl. Amanda's eclectic taste in micro minidresses, sky-high heels, and never a shortage on patterns and prints has us wishing we could raid her closet. From donning killer Lanvin satin pumps and a watercolor-infused Prabal Gurung creation to rocking an electric blue short suit, she knows how to show off her gams with her playful sense of style. Let's review her most magnificent minis on the red carpet to date.
