Check out my latest tutorial to make your very own skeleton costume like the one from American Girl! I even customized mine by changing the tutu to orange and left off the pink heart. I used some basic black shoes to go with the outfit and I could tie some orange ribbon in her hair to simulate the headband that the American Girl version comes with. I also made a pink version (because tulle is so inexpensive, why not make two?) You can make whatever color you want!
Here are the patterns for the leggings and gloves, also the guide for painting the bones on:
For the t-shirt, I used the Liberty Jane Trendy T-shirt pattern. You can get it for free when you sign up for a free account here. I would definitely sign up if you haven’t already–every Friday they pick a new pattern you can download for free. They have so many cute American Girl clothing patterns and even more for other dolls like the Wellie Wishers and Journey Girls!
