Mamma Mia actress Amanda Seyfried looked super cute in this emerald green Jay Godfrey frock. This is a great dress for a number of body types because the sweetheart neckline, cinched waist, and slightly flared skirt do an amazing job enhancing the right places and hiding the oh-so-wrong ones. It's just one of those pieces that will leave you shouting, "It's a miracle! I've just lost 5 pounds instantly but gained perfect curves! No wait... it's just my dress. Nevermind!"
