The dress was inspired by Katy's actual cupcake dress that she wore on her California Dreams tour and is made up of 70 hand-painted, "mini cupcakes".
The doll also features hand-painted tattoos, sparkling pink shoes, a glittered candy cane mic and a waffle-cone stage complete with swirly pops, “ice cream” mountains and cotton candy clouds.
