Most girl scarecrow costumes are made from polyester; product listings frequently list 100% polyester as the fabric.
Listings show suggested ages such as 4–18 years and 5–12 years. Some entries also list “Suggested Age: Adult” even while using Kids sizing labels, so age and size labeling can be inconsistent across products.
Listings cover whimsical fairytale or storybook scarecrow styles as well as scarier horror-style looks labeled Horror, Zombie, or Vampire—so both playful and spooky variants are available.
At least one description highlights a durable, resilient fabric that resists stretching, shrinking, abrasion, and some chemicals. It also notes the costume dries quickly and can be washed and dried to stay fresh.
Descriptions often mention capri-length overalls or pants with straw fringe at the hems, an elastic waist, and a hook-and-loop closure on one side.
