In the stage version of Beauty and the Beast, Belle's dress in the "Something There" number is pink and red with puff sleeves, ruffle edging on the overskirt and underskirt, and the overskirt bunched to make waves of puffs in the fabric (similar to Belle's gold dress in the movie). Her gold dress◊ is made of gauze, with white hanging sleeves, and a trimming with pink flowers.
Glinda wears some in the musical Wicked. There is◊ her ice blue dress with puff sleeves, lace, glitter, and the skirt cut in several wavy tiers. Then there is her pink dress with a small bustier on top, and a short skirt that is several layers of ruffled gauze.
And when other productions do their own costumes, Glinda sometimes gets even more pimped out. In a Danish production, Glinda's bubble dress is white with Opera Gloves, a brocaded bodice, and a gauze skirt covered with white feathers.
Elphaba's Act II dress◊ is fabulous. It's made from up to forty yards of fabric, all stitched together onto the main black dress. And this is all just to make it look like her simple black dress has turned to rags.
