When the love of her life, Ed, announces his surprise engagement to her best friend, Julia Schuster is distraught but determined not to let them see how much she's hurting. She spies a remarkable dress in Shoestring, her sister's designer second-hand shop, and knows she'll only be able to stagger through the wedding day, showing everyone how over Ed she is, if her body is wrapped in its soft silk chiffon. Unfortunately it costs mega bucks and she's barely hanging on to her job as it is.
Arietty Pilgrim can't and won't attend her fiercely competitive school reunion unless she can arrive wearing exactly the same dress. But working as an elephant keeper in Dublin Zoo does not a millionaire make.
But fate has a funny way of bringing people together. Just as Julia starts to flounder amidst family troubles, problem drinking and a broken heart, she meets Arietty and the two of them set up The Shoestring Club - time-sharing one extraordinary dress and beginning a life-altering friendship.
