Mamma Mia, she's a star! Amanda Seyfried is definitely Hollywood's next big thing, and I for one have "big love" for this new star's style! It's not easy for someone as young as Amanda (she's only 23) to look modern and sexy without looking cheesy, but she pulls it off with flying colors.
Some of the best style advice I can give, is figure out what looks good and stick with it! Amanda knows this well sticking to jewel toned cocktail dresses with full skirts and sweetheart necklines. At the London premiere Amanda rocked out in an emerald green Miu Miu and in Berlin a turquoise Jay Godfrey style.
I scouted the web for similar styles you'll fall in love with. Sweetheart necklines are very feminine and flattering and jewel tones work all year round.
To get Amanda's emerald Miu Miu look (see third and fourth pictures to the left), try wrapping some black ribbon around your waist line and wearing a black slip that's longer than your hem.
