Is Beyonce trying out for the NBA? Because the girl sure did rebound from her too-casual, color-blocked pantsuit at the 2013 Grammys in a hurry.

Unlike her sister Solange (who forgot half her outfit), Bey was a golden goddess in a to-die-for shimmery Elie Saab Couture gown with a plunging neckline at the New York City premiere of her vanity project aka documentary 'Life Is But a Dream,' which airs on HBO this Saturday, Feb. 16.

Maybe Beyonce was saving this dress so she could demonstrate more flash and class at her own event, hereby upstaging Music's Biggest Night -- because it's worlds apart from her red carpet blunder earlier this week.

The dress also showed off Queen Bey's killer figure. Hello, hourglass shape. The gown, which skimmed the floor, had movement, and the clusters of gems were sprinkled in all the right places.

It also hugged her badonkadonk. The junk remains in the trunk, even after Blue Ivy's messianic birth.

Enjoy a little low cut plunging neckline action, too. That's one enviable rack.
