Molly and the Magical Dress — William D. Norwich

Molly doesn't want to go to her cousin's stuffy society wedding. She'll be bored -- as always. Worse, her mother insists that she wear a starchy velvet dress. Molly obliges, but also packs into her book bag her favorite dress -- a tattered magic one that allows her to become anyone she wishes. Molly knows that the only way she'll have any fun is by making quick getaways from the hoity-toity celebration and the la-di-da conversation of her relatives. And the magic dress doesn't disappoint! It transports Molly into unexpected adventures of the spirit and the heart. If you believe in the magic dress, anything is possible. . . .
