Personally I would just find the right color Poly lycra knit in the pink/red and then create a stencil for myself, since her wristband, top, and hair bow are 3 different fabrics, I would try to find corresponding fabric pieces and then do the pattern after.
That way, in case you find one printed the way you like the pattern enough for the costume, you can either (Stencil as aforementioned) or use the pattern as a base Idea from one fabric to another.
