For those on a budget why not make your own Kai-lan costume with materials you can find anywhere in your house? Surely you have a plain blue shirt or if not one that can be turned inside out? Attached a small red heart to it and the costume is practically done! Wear orange shorts like this girl does in her homemade Kai-lan costume and then focus on getting the hair right. It’s actually quite easy since you really only need to make sure you have the two red flowers and hair tied into two buns.
