Tips

To make the ponytail stand straight up like Agnes's, wrap a small hair tie tightly around the base multiple times, or insert a brown pipe cleaner into the center of the ponytail.
If you cannot find a pre-striped shirt, a solid yellow t-shirt still works well and is highly recognizable when paired with the overalls.
Keep the unicorn plush close for photos, as it is her most famous prop and instantly identifies the character.
