The vocal powerhouse shined in an icy gown and some cool jewels while singing "Frozen's" Best Song-winning tune on Sunday night. We got the scoop on the goods.

While mesmerizing the Dolby Theatre crowd and at-home Oscars viewers with her rendition of Frozen's "Let it Go," Broadway sensation (and the Oscar-winning film's star) Idina Menzel was stunning in a sheer princess-like Reem Acra dress that looked effortlessly glamorous in blush, powdery and delicate tones. Menzel paired the tulle embroidered gown -- complete with a flowery motif and a flattering corset -- with loose hair, giving the 42-year-old actress an air of eternal youth and power.

The look's piece de resistance, however, was a solo Forevermark diamond chain finger bracelet, which gracefully encircled her left wrist. A standing ovation was the least she could get.
