The windows, "styled with Nudie denim and dedicated to the hit show," will be introduced at 4:15 PM followed by a poster-signing event featuring John Gallagher, Jr., Tony Vincent, Stark Sands, Michael Esper, Rebecca Naomi Jones, Mary Faber and Christina Sajous.
After the ribbon-cutting ceremony, customers are invited to meet the cast. The first 50 guests will receive an American Idiot t-shirt, and the first 100 customers will receive a poster for the cast to sign. Plus, ten people will be chosen at random to receive free tickets to the show.
Customers who make a purchase of $200 or more in men's or women's Nudie denim will also receive two free tickets to see American Idiot.
The signing event will be in the second floor of Bloomingdale's.
American Idiot, inspired by the 2004 punk album of the same name, opened April 20 at Broadway's St. James Theatre. Michael Mayer co-wrote the book with Green Day frontman Billie Joe Armstrong, with songs by Armstrong and Green Day. Visit AmericanIdiotonBroadway.com.
