Country gal Carrie Underwood stepped onto the Grammy Awards stage Sunday night in a billowing Theia princess gown.

It would have been another boring stage costume, had Underwood’s silver dress not turned into a visually-stimulating sequence of special effects, bursting with bright colors, floral patterns and crazy lights. The gown, which had to be approved in advance by the show's video coordinators, was largely executed by Theia creative director Don O'Neill and his team.

By the numbers, it took three days, thousands of Swarovski crystals, 10 yards of Duchesse satin, 100 yards of tulle, and a full production team to create Carrie Underwood’s gown at the Grammys Sunday night.
