One aspect of the universe in the Wicked film franchise that will be explored in depth in the upcoming sequel, Wicked: For Good, is through âThe Girl In The Bubbleâ, one of the key songs in the film for Glinda, the Good Witch, where she confronts her privilege and having to make difficult decisions in her role. This flannel shirt from Cakeworthy, with a lilac check print, perfectly reflects this, with the song title printed on the back, and embroidered detailing on the front pockets and collar.
