Thirteen-year-old Diana is not thrilled about having to help out at her family's none-too-glamorous dry cleaning business every day after school. But Diana soon discovers that the place has a secret: In the back room, the smart, savvy tailors sometimes try on--and borrow--the cool clothes. When Diana is modeling a luxe coat, she finds in its pocket the invitation to a Broadway gala opening...and decides to assume the role of the coat's owner--and go to the event!
