>>7211723>There's no Dorothy Gale so Glinda is taken out of her pink dress, and is popped into a blue dress as a Dorothy surrogateShe's actually in blue because Glinda wearing a big pink gown in the MGM film made it legally tricky to use it in the show. Nothing to do with Dorothy.
From the designer, in regards to the original blue 'bubble gown':
>When I was designing the show originally, we had the rights to use only the W. W. Denslow illustrations from the original L. Frank Baum book, and had no rights to anything that was connected to the movie. I actually had to prepare a brief for the production’s lawyers describing why I wanted to use a full skirted dress like this in order to show that I wasn’t taking what Adrian did in the original movie. All my reasons had to do with what Lady Di wore for her wedding dress, as well as what Queen Elizabeth wore. The other reason we are able to use the bubble influence is because in one of the other original Wizard of Oz books, the Wizard actually created a bubble machine, so the idea of bubbles and air actually comes from the Oz books. Then when they redesigned the gowns at the start of the national tour launch, the success of the musical made it easier to poof up the gown even further.
