Beyoncé's HBO documentary, Life Is But a Dream, debuts this Saturday, but first, the singer stunned in an embellished Elie Saab gown — from the house's Spring 2012 Couture collection — and Lorraine Schwartz jewels at the NYC premiere tonight. We would expect nothing less than dazzling from Beyoncé for her big night. Everything from the sheer bodice to the floral appliqué detail to the neutral color is undeniably exquisite, especially on her gorgeous figure. And clearly Beyoncé is also in love with her dress, because she posted this side shot on her Instagram. Without further ado, click on to see all sparkly angles of the singer's spotlight-worthy Elie Saab gown.
