Halloween costume

This morning, I've been trying to get the mountain of wrinkles out of Sophie's SuperGirl costume with little (OK...NO) success. Can you imagine a garment with the following laundry instructions: "Do not iron. Do not dry clean. Do not wash. Wipe with damp cloth." Poor planning on my part to say the very least! Who on earth intentionally buys a garment for a 4 year old child that cannot even be WASHED? Guess she'll just be cute and wrinkled.
