The Sisterhood of the Traveling Pants (2005)

The movie is based on the young adult book, The Sisterhood of the Traveling Pants, by Anne Brashares. As four best friends spend their first summer apart from one another, they share a magical pair of jeans. Despite being of various shapes and sizes, each one of them fits perfectly into the pants. To keep in touch they pass these pants to each other as well as the adventures they are going through while apart.
