This is a homemade costume requested by daughter who was nine at the time. She wanted to be a black widow spider. I made it by stuffing black tights with newspaper, cutting along the seam of a black shirt, inserting the stuffed tights and then hot gluing it shut again.
I used ribbon to attach all the legs to each other so they would stay up and move along with her arm. The felt hourglass shape was cut out of felt and glued on the shirt. The skirt, spiderweb leggings and wig were all bought and added to complete her spider look. She was excited to win in two different costume contests with this!
